Find the surface area of the cylinder with a height of 11cm and 4cm as a base

I hope this helps you

Step-by-step explanation:

I believe you meant "radius of the base is 4 cm."

The vertical sides of this cylinder have the area A = 2πr*h, where r is the radius of the base and h is the height of the cylinder.

Here, that comes out to A = 2π(4 cm)(11 cm) = 88π cm^2.

If the "surface area" is to include the top and bottom as well, add the following to 88π cm²:

2[πr²]  =  2(π[4 cm]² = 32π cm²

Area of side alone:                 88π cm²

Area of top and bottom:        32π cm²

Total surface area:               88π + 32π    cm²
