The formula for the volume of a sphere is:

V = 4/3 * PI * r^3

The diameter is given as 21.6, divide this by 2 for the radius:

R = 21.6 / 2 = 10.8

V = 4/3 * PI * 10.8^3

V = 5276.7 cm^3

The answer is D

Answer:

D) 5276.7 cm3

Step-by-step explanation:

Volume of a sphere is given by

V = 4/3 *pi*r^3

We are given the diameter. The diameter is twice the radius

d =2r

21.6 = 2*r

21.6/2 = 2r/2

10.8 =r

Now we can find the volume,

V = 4/3 * pi *(10.8)^3

V =5276.669286
