Question

Find the volume of a sphere with a diameter of 18.8 cm, . Use 3.14 for π. Round your answer to the nearest tenth.

Answer 1

volume of a sphere =
`(4)/(3) \pi r^(3)`

Radius = 18.8/2 = 9.4 cm

volume of the required sphere =
`(4)/(3) \pi (9.4)^(3)`

=
`(4)/(3)(3.14)(9.4)^(3)`

=3477.4 cm^3 (cor to nearest tenth)
