Question

Total surface area of a sphere is 452 4 by 7 cm square find its radiusplease answer fast​

Answer 1

Answer:

given:- surface area of sphere= 3168/7. and let the radius be r cm.

4*pi*r2= 3168/7

r2= 3168/7*7/22*4

r2= 36.

r=6cm.

volume of sphere= 4/3*pi*r3.

4/3*22/7*6*6*6= 6336/7cm3.

so the volume of sphere is 6336/7 or 905.14cm3....
