A cylinder has radius of 4 inches and height 10inches.There’s a small cylinder inside the previous cylinder of radius of 2 inche
s with the same height and same centre.What is total surface area?
1 answer:
The surface area of the cylinder is 48π inches².
<h3>How to find the Surface area of a cylinder?</h3>
Surface area of a cylinder = 2πr(r + h)
where
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
