A hard candy has a radius of 9 mm. The candy has a spherical soft center with a radius of 6 mm, with a hard shell surrounding it.

What is the volume of the hard shell?

Use 3.14 to approximate pi and express your final answer in hundredths.

mm3

Well you have to subtract the soft shell volume from the entire candy volume. Using the formula for the volume of a sphere, the whole candy is 4/3*729*3.14=3052.08

the soft center is 4/3*216*3.14 = 904.32. If you subtract, you get the answer of 2147.76 mm^3.
