Answer:

The slope is 9.

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
