Question

the volume ofa sphere is38808cm3 findits radius amd hence itssurface area

Answer 1

here is your answer
so the volume of the sphere is 38808cm^3
imagine that the radious is r cm then according to the question,

4/3 πr^3= 38808
or, r^3=38808×3/4×7/22
or, r^3=441×3×7
or, r=21 cm

so,the radious of the sphere is 21cm.
its surface area will be
=4×22/7 × 21×21 cm^2
= 5544 cm^2 ( Answer)
