The surface area of a sphere is 200.96 square centimeters. what is the approximate volume of the sphere?

We know that
surface area of sphere=4*pi*r²
r=√[surface area/(4*pi)]
for surface area=200.96 cm²
so
r=√[200.96/(4*pi)]> r=4 cm

volume of a sphere=(4/3)*pi*r³> (4/3)*pi*4³> 268.08 cm³

the answer is
the approximate volume of the sphere is 268.08 cm³
