A cylinder has radius of 4 inches and height 10inches.There’s a small cylinder inside the previous cylinder of radius of 2 inches with the same height and same centre.What is total surface area?

Respuesta :

The surface area of the cylinder is 48π inches².

How to find the Surface area of a cylinder?

Surface area of a cylinder = 2πr(r + h)

where

  • r = radius
  • h = height

Therefore,

Surface area of the smaller cylinder = 2 × π × 2(2 + 10)

Surface area of the smaller cylinder = 4π(12)

Surface area of the smaller cylinder = 48π
