Answer:
♦ yes the surface of the sphere equal to
the 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
