If the diameter of a youth baseball is 2.8 inches and the diameter of an adult softball is 3.8 inches, what is the approximate d
ifference in their volumes? Use 3.14 for pi . Round to the nearest tenth.
2 answers:
volume = 4/3 x 3.14 x r^3
4/3 * 3.14 = 4.18666
radius of youth ball = 2.8/2 = 1.4
volume = 4.18666 x 1.4^3 = 11.488 cubic inches
radius of adult ball = 3.8/2 = 1.9
voulume = 4.18666 x 1.9^3 = 28.716
28.72 - 11.49 = 17.2 cubic inches difference
