Answer:

216π sq ft

Step-by-step explanation:

given that :

d = 12 ft => r = 12/2 = 6ft

h(cyl) = 10 ft

h(cone) = 8 ft

the surface area = ?

the solution :

the slant of cone = √r²+h²

= √6²+8²= √100 = 10 ft

the surface area of silo =

the lateral area of cone + the lateral area of cylinder + the base area

= π×r×slant + 2×π×r×h(cyl) + π×r²

= π×6×10 + 2×π×6×10 + π×6²

= 60π + 120π + 36π

= 216π sq ft

The surface area of the silo will be 216π square feet. Then the correct option is C.

It deals with the size of geometry, region, and density of the different forms both 2D and 3D.

A silo consists of a cone stacked on top of a cylinder, where the radii of the cone and the cylinder are equal.

The surface area is the sum of the surface area of the cone and cylinder. Then we have

The diameter of the cylindrical base of the silo is 12 ft and the height of the cylinder is 10 ft, while the height of the cone is 8 ft.

Surface area = πrl + 2πrh + πr²

The length of the radius will be

r = d /2

r = 12 / 2

r = 6 ft

The length of slant height will be

l² = 6² + 8²

l² = 100

l = 10 ft

Then the surface area of the silo will be

SA = π × 6 × 10 + 2π × 6 × 10 + π6²

SA = 60π + 120π + 36π

SA = 216π square feet

The surface area of the silo will be 216π square feet.

Then the correct option is C.

Answer:

1. 452.39

2. 615.75

Step-by-step explanation:

area of a circle = A=πr2

Answer:

The answer is A

Step-by-step explanation:

This I because the area of a square is =

(length of on side)² = l²

The options there are not perfect squarss except A

which is 64 in²

And we know that 8² will give you 64

so then it means one side is 8 in

So the area =

8² = 8 in × 8 in = 64 in²

Answer:

Step-by-step explanation:

to prove it right angle

square of largst side must be eqaul to the sum of two other sides.

so here 12 is largest and 11 and 5 are two other smallest sides of a triangle.

(12)^2=(11)^2+(5)^2

144=121+25

144=146

since the square of largest side is not equal to the sum of square of other two smaller sides it can be concluded that the given sides of a triangle does not form a right angled triangle.

Step-by-step explanation:

Janet would be 8 cause yeah

Answer:

15$

Step-by-step explanation:

this is because if you use our formula of I= prt

we can substitute our varibles for our equation

I= 300 x 0.05 x 1

we turn 5 in 0.05 to represent out rate, due to this our rate would have to be Simplified into a percent then a decimal

after this if we now proceed through our equation we will get

I = 300 x 0.05 x 1

I = 15

Answer:

Circumference of circle = (15.5)π cm

Step-by-step explanation:

Missing information:

Area of circle = 60π cm²

Find:

Circumference of circle

Computation:

Area of circle = πr²

Area of given circle = π(Radius of circle)²

60π = πr²

60 = r²

Radius of circle = 7.75 cm  (Approx)

Circumference of circle = 2πr

Circumference of circle = 2(π)(7.75)

Circumference of circle = (15.5)π cm

Answer:

x = 2, y = - 1

Step-by-step explanation:

Given the 2 equations

y = - 7x + 13 → (1)

y = - 1 → (2)

Substitute y = - 7x + 13 into (2)

- 7x + 13 = - 1 ( subtract 13 from both sides )

- 7x = - 14 ( divide both sides by - 7 )

x = 2

y = - 1 is already given in (2)

Then x = 2, y = - 1

Answer:

x = 12.35

Step-by-step explanation:

Tan(39) = 10/x

Tan(39) * x = 10

x = 10 / Tan(39)

x = 12.35

Hope this helps!

Answer:

Step-by-step explanation:

Remember SOHCAHTOA.

In this case, we use TOA.

tan(39) = 10/x

x = 10/tan(39)

x = 12.349

Answer:

V = 75 pi

Step-by-step explanation:

We know the volume of a cylinder is given by

V = pi r^2 h where r is the radius and h is the height

V = pi ( 5)^2 (3)

V = pi (25)(3)

V = 75 pi

===============================================

Work Shown:

r = 5 is the radius

h = 3 is the height

V = pi*r^2*h .... volume of a cylinder

V = pi*5^2*3

V = pi*25*3

V = pi*75

V = 75pi ..... exact volume in terms of pi

V = 75*3.14

V = 235.5

If you used the approximation pi = 3.14, then the approximate volume is about 235.5 cubic units. Use more decimal digits of pi to get a more accurate answer.

Note how the pi*r^2 portion represents the area of the circular base. So we can say

volume = (area of base)*(height)

Answer:

Step-by-step explanation:

Given :

Salary in 2016 = 1750

Pay rise in 2017 = 2%

Monthly salary = (1 + 2%) of 175= 1.02 * 1750 = 1785

Hours worked per week = 45 hours

Number of weeks = 48 weeks

The total hours worked for the year :

(48 * 45) = 2160 hours

Average pay per hour for the year ;

(Average Salary earned over 12 months) /total number of hours worked for the year

(1785 * 12) / 2160

= 21420 / 2160

= 9.9166 per hour

Answer:

44 euros

Step-by-step explanation:

if the ratio between an english pound and a euro is 3 to 4 respectivley, the ratios will hold true for any number. Since 33/3 = 11, we can stratigically multiply by 1,

3/4 = (3/4)(11/11)

so the ratios would be the same, multiplying, you would get 33/44, which means 33 pounds for 44 euros
