Question

Approximate the volume of the solid. *round your answer to the nearest tenth.

Answer 1

vol of sphere = 4/3 x pi x r^3
4/3 x pi x 2^3
=32/3 pi
1/2 sphere so divide by 2 = 16/3 pi

Vol of cylinder= pi x r^2 x h
pi x 2^2 x 4
=16 pi

16/3 pi + 16 pi =64/3 pi or 67.02 cm^3

Rounded to nearest 10 = 70cm^3

Answer 2

83.8 cm^3

Explanation:

Volume of Cylinder = πr^2h

Volume of Full Sphere = 4/3πr^3
