1. To solve this problem, you must aplpy the formula for calculate the volume of a sphere, which is:
 
 V=4/3(πr)
 
 V is the volume of the sphere.
 r is the radius of the sphere.
 
2. You must calculate the radiius. You have that the beach ball has a diameter of 18 inches, then:
 
 r=diametert/2
 r=18 inches/2
 r=9 inches
 
 3. When you substitute r= 9 inches into the formula, you obtain:
 
 V=4/3(πr)
 V=3053.62 inches³
