Question

the surface area of a sphere is452.57cm2 then find the volume of a sphere

Answer 1

hope this will be helpful if yes ... mark as a brainiest answer

Answer 2

TSA of sphere =
$4\pi {r}^{2}$
its given 452.57cm^2

Now,
$4\pi {r}^{2}$
4 x 22/7 r^2 = 452.57

(452.57×7)/22×4

r^2 = 35.99
r = 5.9
volume = 4/3 pie r ^3
4/3 × 22/7 5.9^3
= 18073.352 / 21
= 860.6 cm^3
