Question

What is the volume of a sphere with a diameter of 15 cm? Round the answer to the nearest whole number.

Answer 1

1767 cm³

Explanation:

We can use volume V = 4/3 π r³

We have diameter of 15 cm. To get radius, we need to divide diameter by 2.

r = 7.5 cm

So now plug in r = 7.5 then calculate V:

V = 4/3 π ( 7.5 )³

V = 4/3 π * 421.875 ≈ 1767.145 ≈ 1767

Hope this helps.
