Answer:

h = S/(2 π r) - r

Step-by-step explanation:

Solve for h:

S = 2 π r (r + h)

S = 2 π r (r + h) is equivalent to 2 π r (r + h) = S:

2 π r (r + h) = S

Divide both sides by 2 π r:

r + h = S/(2 π r)

Subtract r from both sides:

Answer: h = S/(2 π r) - r

Answer:

h=s/(2 π r) -r

Answer:

409

Step-by-step explanation:

This is very easy. First of all you need to workout out 1/10 of the value of the 9 in 296. The value of the 9 in 296 is 90.

1/10 of 90 is 9 (since 1/10 x 90 = 90/10 = 9)

The only number which has 9 as its final digit is 409

Answer:

12:18 and 10:12 (i think)

Step-by-step explanation:

After converting the given ratios in their simplest form, the equivalent form of 2:3 we get 12:18.

To find the simplest form of a fraction, you have to simplify the numerator and denominator to their lowest terms and keep dividing until you can no longer simplify the fraction any further.

The given ratios are,

12:18,

3:21,

10:12

For the ratio 12:18,

Simplify it by finding the greatest common divisor (GCD) of 12 and 18.

The GCD of 12 and 18 is 6.

By dividing both numbers by 6, we get the smallest ratio of 2:3.

Moving to the ratio of 3:21,

Find the GCD of 3 and 21, which is 3.

Dividing both numbers by 3 results in the smallest ratio of 1:7.

Find the smallest ratio for 10:12.

The GCD of 10 and 12 is 2.

Dividing both numbers by 2 gives us the smallest ratio of 5:6.

Hence, the simplest form of ratios for the given ratios are:

12:18 = 2:3,

3:21 = 1:7,

10:12 = 5:6.

Hence,

The ratio equivalent to 2:3 is 12:18.

Step-by-step explanation:

Answer: x+5/8 = 1 is the equation where x is the remaining coffee.

Step-by-step explanation:

he drank = 5/8

whole coffee = 1

so

let coffee remaining be x

1-5/8 = x

x+5/8 = 1

The required equation, for the remaining cup of coffee, is x = 1+(- 5/8).

To determine the addition equation of coffee remaining in the cup, for the condition Kelly bought a cup of coffee and drank 5/8 it.

In mathematics, it deals with numbers of operations according to the statements. There are four major arithmetic operators, addition, subtraction, multiplication and division,

The process in mathematics to operate and interpret the function to make the function or expression simple or more understandable is called simplifying and the process is called simplification.

Here,
Let the coffee remaining in the cup be x,
Now, according to the question,
1 = x + 5/8
x = 1 - 5/8
For the addition equation,
x = 1 +(-5/8)

Thus, the required equation, for the remaining cup of coffee, is x = 1+(- 5/8).

Step-by-step explanation:

it is really not complicated. we only need to type the numbers into the calculator.

so, what's the problem ? you don't know what a perimeter is ? it is the circumference, the total way you have to go when waking all around the figure.

you don't know the formulas for the areas of specific figures ?

let's start :

a)

the area of a rectangle is length×width. I hope you know this at least since first grade.

the important thing here is : the result is in² and not just in. it means an area counts the little squares that fill that area.

A = 30×8 = 240 in²

the perimeter, as explained, is the whole way around it. so, in the end, as you can easily see, we would have to go 2 times the long side and 2 times the short side.

the result is in (just a length, a distance not an area, not a cube, ...).

P = 2×30 + 2×8 = 60 + 16 = 76 in

b)

the area of a triangle is

baseline × height / 2

in this case (a right-angled triangle) we can assume one of the sides enclosing the 90 degree angle as baseline and the other as height (since there is already a 90 degree angle between them).

and again, the result is ft². we could express it also e.g. as in², but since the basic measures are in ft, it makes it better understandable to use ft².

A = 12×5/2 = 6×5 = 30 ft²

the perimeter is even easier than for the rectangle, as we have one side less to count.

and as before, we stay with ft.

P = 12 + 13 + 5 = 30 ft

c)

this is the only more special case.

but it is still easy.

the area is baseline × height.

and our unit of measurement here is cm, so the result will be cm².

A = 10×2 = 20 cm²

the perimeter is the same principle as with a regular rectangle, as the angles don't matter. only the side lengths matter.

so, again, while waking around it, we have to pass 2 times the long side and 2 times the short side.

and the result is a length, a distance again, so, it is cm.

P = 2×10 + 2×4 = 20 + 8 = 28 cm

Answer:

2x^11

Step-by-step explanation:

distributing x^8(2x^3) makes 2 * x^3 * x^8. To multiply exponents, just add the powers together to make 11. This makes 2x^11.

Answer:

[tex]8x^1^1[/tex]

Step-by-step explanation:

Hi there!

[tex]x^8*(2x)^3[/tex]

Distribute the exponent into the parentheses:

[tex]= x^8*2^3x^3\\= x^8*8x^3\\= 8*x^3*x^8[/tex]

When two powers have the same base, add the exponents:

[tex]= 8*x^3^+^8\\= 8*x^1^1\\= 8x^1^1[/tex]

I hope this helps!

Step-by-step explanation:

a) is really easy, right ?

the surface area consists of 6 rectangles (as you know, every die has 6 sides). they are 3 pairs of equally sized rectangles.

there are 2 rectangles 7×1, 2 rectangles 7×2, and 2 rectangles 2×1

SA = 2×7×1 + 2×7×2 + 2×2×1 = 14 + 28 + 4 = 46 in²

the volume is just length×width×height

V = 7×2×1 = 14 in³

b)

a little bit more difficult, but with a little trick just as easy.

the surface area consists of the 2 circle areas and the mantle "coating".

the area of a circle is pi×r².

we have to be careful as the given 10 ft is the diameter of these circles. the radius is half of it : 5 ft.

the area of the "mantle" we can calculate by imagining we simply slice it open with one straight line from top to bottom. and then we cut it off the two circles and put it flat on the table.

now we see it is just a rectangle. one side is 12ft. the other is the circumference of the previously attached circles.

circumference of a circle is 2×pi×r

so the surface area is 2×circle + (circumference circle)×12

SA = 2×pi×5² + (2×pi×5)×12 = 50pi + 120pi = 170pi =

≈ 534.07 ft²

the volume is one base area (circle) times height

V = pi×5²×12 = 300pi ≈ 942.48 ft³
