Question

A sphere has a diameter of 10 inch. What is the volume of the sphere?

Answer 1

Answer:

≈ 523.6 in³

Step-by-step explanation:

The volume (V) of a sphere is

V = $\frac{4}{3}$ π r³ ← r is the radius

here diameter = 10, hence r = 5, so

V = $\frac{4}{3}$ π × 5³

  = $\frac{4}{3}$ π × 125

  = $\frac{4\pi (125)}{3}$ ≈ 523.6 ( to 1 dec. place )
