Abeach ball has a radius of 9 inches what is the volume

V=4/3pir^3
r=9
V=4/3pi9^3
v=4/3pi729
V=972pi

if want, aprox pi=3.141592
V=3053.627424 in^3

Solutions 

The volume of a sphere is given by the formula V = 4/3 πr³ , where V is the volume of the sphere and r is its radius. We know that the radius is 9 inches. 

Calculations 

Formula = V=4/3πr³

V=4/3πr³

v=4/3πr³ ( 9 ) = r

r³ = 9 x 9 x 9 = 729

V=972π 

The answer would be the second choice : )
