Question

Find the volume of the sphere shown. Give each answer round to the nearest cubic unit. 15 CM

Answer 1

a

Explanation:

the volume (V) of a sphere is calculated as

V =
`(4)/(3)`πr³ ( r is the radius )

here the diameter = 15, then r = 15 ÷ 2 = 7.5 , then

V =
`(4)/(3)`π × 7.5³

=
`(4)/(3)`π × 421.875

=
`(4\pi (421.875))/(3)`

≈ 1767 cm³ ( to the nearest cubic cm )
