Question

find the surface and the volume of a sphere of radius 60cm. take (py=3.14)

Answer 1

surface area becomes 2712900 cm square.
volume of sphere becomes 904320 cm cube.

Answer 2

Given,
radius = 60cm.
surface area of shpere =?
total surface area = 4πr^2
= 4×3.14×60×60
= 4×3.14×3600
= 14400×3.14
= 45216 cm^2 //answer

Volume of sphere = 4/3×πr^3
= 4/3×3.14×60×60×60
= 4×3.14×72000
= 288000×3.14
= 904320 cm^3


I hope it will help you....!!
