Question

Find the volume of a sphere with a diameter of 8cm

Answer 1

268.1 cm^3

Explanation:

The formula for the volume of a sphere of radius r is V = (4/3)(pi)(r)^3.

If the diameter of this sphere is 8 cm, then the radius is 4 cm, and r^3 = 64 cm^3. Thus, the volume is:

V = (4/3)(3.14)(64 cm^3) = 268.1 cm^3

Answer 2

V = 267.95

Explanation:

Volume of a Sphere:

V = 4/3πr³

r = d/2

r = 4

Work:

V = 4/3πr³

V = 4/3(3.14)(4³)

V = 4/3(3.14)(64)

V = 267.95
