Question

Find Volume
A sphere has a radius of 1.5 feet.

Answer 1

V=14.14ft^3

Explanation:

V=4/3(π)1.5^3

=4/3(π)3.375

=14.14ft^3

Answer 2

14.1 ft³ (to 3 s.f.)

Explanation:

`\boxed{volume \: of \: sphere = (4)/(3)π{r}^(3) }`

Given that the radius is 1.5 feet, substitute r= 1.5 into the formula above:

Volume of sphere

`= (4)/(3) (π)( {1.5}^(3) ) \\ = 14.1 \: ft^(3)`

(to 3 s.f.)
