Answer:
Volume of the sphere=2.7×10^-8m^3
Step-by-step explanation:
Given:
C.S.A=452 4/7= 3168/7
Curved surface area of sphere (C.S.A)=4πr
3168/7= 4×3.14×r
r= 3168/7× 4×3.14
r= 3168/87.92
r= 36.032 cm^2
r= 36.032×1/10000
r= 36.032/10000
r= 3.6032×10^-3m^2
r= 3.6032/1000
r= 0.003m^2
Volume of the sphere= 4/3πr^3
= 4/3×3.14×(0.003)^3
= 2.7×10^-8m^3
I hope this will help you
