Question

What is the volume of the sphere?

Answer 1

V(sphere) = 4·π·r³/3

d = 2r => r = d/2 = 8ft/2 = 4 ft

V = 4·π·48/3 ft³

= 192·π/3 ft³

= 64π ft³

= 200,96 ft³

π = 3,14

Answer 2

Explanation:

But the formula for the volume of a sphere is volume is equal to 4/3 pi r cubed, where r is the radius of the sphere. So they've given us the diameter. And just like for circles, the radius of the sphere is half of the diameter.
