the surface area of a sphere is 452 4/7cm^2.what is its volume?

Answer 1

Answer:

904.78 cm

Step-by-step explanation:

surface area of sphere = 3168/7

let the radius be 'x' cm

$4*\pi *r^{2}$ = 3168/7

x square = 3168/7*7/22*4

x square = 36

x = 6 cm

volume = $\frac{4}{3} *\pi *r^{3}$

             = 4/3*22/7*6*6*6

             = 904.78 cm
