What Is The Lateral Area Of The Cone To The Nearest Whole Number? The Figure Is Not Drawn Toscale.15,080

Answers

Answer 1

Answer:

The lateral surface area of the cone is [tex]25120\ m^2[/tex].

Step-by-step explanation:

We have.

Height of a cone is 60 m

Diameter of a cone is 10 m

Radius, r = 80 m

The lateral surface area of a cone is given by :

[tex]A=\pi rl[/tex]

l is slant height of the cone,

[tex]l=\sqrt{60^2+80^2} =100\ m[/tex]

Plugging all values in above formula,

[tex]A=3.14\times 80\times 100\\\\A=25120\ m^2[/tex]

So, the lateral surface area of the cone is [tex]25120\ m^2[/tex].

Answer:

A

Step-by-step explanation:

If you were to multiply the top by 7 then add you would cancel out the x and if you were to multiply the bottom by 6 then when you use the subtraction method you multiply the top by negative and if that were to happen you would do -6x + -6x which would cancel nothing out. But if you just add the two equations nothing would cancel out.

Hope this helped!

Answer:

A

Step-by-step explanation:

If you multiply the top by 7, when you add you can cancel out -7x and 7x. The second one doesn't work because it said subtract at the end. If you subtract then it won't cancel out the y's.

Find the volume of a cylinder when the radius is 9 cm and the length is 20 cm

Answers

Answer:

5089.38 cm OR 1620π

Step-by-step explanation:

The formula for the volume of a cylinder is π[tex]r^{2}[/tex]h so if the radius is 9, 9 squared is 81. We multiply 81 by 20 and that gives us 1620. So in terms of pi, it is 1620π but if you just multiply it all together, it gives you 5089.38 cm. Please mark me brainliest and I hope this helped!

Based on the radius and the length of the cylinder, we can calculate that its volume is 5,091.43 cm³.

The volume of a cylinder can be calculated by the formula:

= π x radius² x height

Solving will give:

= π x 9² x 20

= π x 81 x 20

= 5,091.43 cm³

In conclusion, the volume is 5,091.43 cm³

Answer:

155.7

Step-by-step explanation:

Use what you know.

Segment AC is 130 ft

Segment CD is 70ft

If you use the Pythagorean Theorem, in this case being  =  +

To find segment CE, you would do r-70

So,  =  +

= 16,900 +  -140r + 4900

Add the -140r to the left side and then get rid of the two . Then Add 16,900 and 4900 together

You'll end up with 140r = 21,800

Divide 140 on each side.

Pythagorean Theorem: Jason only has room for a TV that is less than 30” wide.
Can he fit the TV in his room?

Answers

Answer:

No

Step-by-step explanation:

Using the Pythagorean Theorem, make 40 = c, 24 = b and the remaining side (the width) = a.

Solving for a we get a = [tex]\sqrt{c^2-b^2}[/tex]. Then plugging in the values for c and b, we get a = [tex]\sqrt{1024}[/tex] = 32

Since the width of the TV needs to be less than 30" wide, it will not fit since the width of the TV is 32" wide.

Answer:

No, the tv is 32 inches wide.

Step-by-step explanation:

[tex]a^{2} +b^{2} = c^{2} \\24^{2} +b^{2} =40^{2} \\40^{2} -24^{2} =b^{2} \\1600-576=b^{2} \\1024=b^{2} \\\sqrt{1024} =b\\b=32[/tex]

On a coordinate plane, triangle A B C has points (negative 3, negative 1), (negative 2, negative 3), (1, negative 1) and is reflected across y = 1. Reflect the figure over the line y = 1. Which is point A’ after the reflection? A’(–3, 1) A’(–3, 3) A’(–3, 2) A’(1, 1)

Answers

Answer:

A' = (-3, 3)

Step-by-step explanation:

If the points are as follows:

A = (-3, -1)

B = (-2, -3)

C = (1, -1)

When reflecting across a y axis the x values remain the same.

When reflecting across y = 1 the y values will remain equal distant from y = 1.

A' = (-3, 3) y value = |-1 - 1| = 2 + 1 = 3

B' = (-2, 5) y value = |-3 - 1| = 4 + 1 = 5

C' = (1, 3) y value = |-1 - 1| = 2 + 1 = 3

A line passes through the point (1,-3) and has a slope of -7. Find the equation of the line.

y = -7x+4

Step-by-step explanation:

We can use the slope intercept form of the equation

y = mx+b where m is the slope and b is the y intercept

We know the slope

y = -7x+b

We have a point to substitute in for x and y

-3 = -7(1) +b

-3 = -7+b

Add 7 to each side

-3+7 =b

4 =b

We can substitute this back into

y = -7x+b

y = -7x+4

Answer:

y+-7x+4
