The volume of a cylinder is numerically equal to its curved surface area, then find the diameter of the cylinder

PLS I WILL MARK AS BRAINLIEST

Answer 1

Answer:

Let r be the radius of the sphere. 

and Volume of a sphere = surface area of the sphere 

⇒ 4 / 3πr3 = 4πr2

⇒ r = 3 cm 

∴ Diameter of the sphere = 2r = 2 × 3 = 6 cm
