Question

The diameter of a sphere is 4 centimeters. Which represents the volume of the sphere?

이 me
O 81 cm
O 64 cm
O 167 cm

Answer 1

V = 33.5 cm^3

Explanation:

The volume of a sphere is given by

V=4/3 pi r^3

The diameter is 4

r= d/2

r =4/2 =2

V = 4/3 pi (2)^3

V = 4/3 pi 8

V = 32/3 pi

Assuming pi is approximated by 3.14

V = 32/3 (3.14)

= 33.493333333 cm^3

To the nearest tenth

V = 33.5 cm^3
