Exercise 13 Page 456

Use the formula for the volume of a sphere.

5575.3cm^3

Practice makes perfect

The given solid is a sphere.

We will use the formula for the volume of a sphere to get the volume. V=4/3π r^3 We know that the diameter is 22 centimeters. We will divide the diameter by 2 to find the radius! r=22/2= 11 Now we can substitute this value into the formula to get the volume.

V=4/3π r^3

Substitute

r= 11

V=4/3π ( 11)^3
