Question

the diameter D of a sphere is 13m calculate the sphere volume V use the value 3.14 round your answer to the nearest tenth

Answer 1

1149.8 m³

Explanation:

The volume (V) of a sphere is calculated as

V =
`(4)/(3)`πr³ ( r is the radius )

Here diameter = 13, thus radius = 13 ÷ 2 = 6.5

V =
`(4)/(3)` × 3.14 × 6.5³

=
`(4)/(3)` × 3.14 × 274.625

=
`(4(3.14)(274.625))/(3)` ≈ 1149.8 m³ ( to the nearest tenth )
