The approximate difference in their volumes is 17.2 cubic inches
A sphere is a round solid figure, with every point on its surface equidistant from its centre.
The formula for calculating the volume of a sphere is;
V = 4/3πr³
where:
r is the radius of the sphere
Given the following
diameter of youth ball =2.8in
radius of youth ball r = 1.4in
diameter of adult ball =3.8in
radius of adult ball R = 1.9in
Determine the difference in volume
D = 4/3π(R³ - r³)
Substitute
D = 4/3π(1.9³ - 1.4³)
D = 4/3π(4.115)
D =17.2 cubic inches
Hence the approximate difference in their volumes is 17.2 cubic inches
