Question

A sphere is inscribed in a cylinder Is the surface area of the sphere equal to the CSA of cylinder?if yes ?explain​

Answer 1

Step-by-step explanation:

Answer. yes the surface of the sphere equal to curved surface area of the cylinder. But the surface area of cylinder is 2pi r(r+h)

Answer 2

yes, the surface of the sphere equal to curved surface area of the cylinder.

surface area of cylinder=2pi × r^2 ×h

h=diameter of cylinder/sphere

=2r

therefore surface area of cylinder=2×pi×r^2×2r

=4×pi×r^3

which is equal to the surface area of sphere that is 4×pi×r^3
