Question

what is the total surface area of a regular cylinder​

Answer 1

Answer:

Explanation:

To find the surface area of a cylinder add the surface area of each end plus the surface area of the side. Each end is a circle so the surface area of each end is π * r2, where r is the radius of the end. There are two ends so their combinded surface area is 2 π * r2.

Answer 2

General formula for the total surface area of a regular cylinder:

T.S.A.= 2πrh+2πr2

Explanation step by step:

To find the surface area of a regular cylinder add the surface area of each end plus the surface area of the side.

Each end is a circle so the surface area of each end is π * r2, where r is the radius of the end. There are two ends so their combinded surface area is 2 π * r2.
