3. find the volume of the sphere pictured below. the sphere has a radius of 20 cm. use 3.14 for pi. give your answer to the nearest tenth. show your work to receive full credit.

A.

3.

Step-by-step explanation:

A. Given: Height of cylinder = 21 ft.

Diameter=10 ft

then Radius =

The volume of cylinder is given by :-

3. We know that the volume of a sphere is given by :-

, where r is the radius of the sphere.

Given : The radius of the sphere =20 cm

Now, the volume of the sphere will be :-

(sin 42)/31. = sinx)/37

sinx = 37 (sin42)/31

= 37× 0.66/31 = 0.787

x= 51.9

other angle opposite to y = 180-51.9-42

= 180- 93.9 =86.1

so

sin42)/31 = sin 86.1)/y

0.021 = 0.997 /y

y= 0.997/0.021 =47.47
