Question

What is the formula for the surface area of a cylinder?

Answer 1

`color(brown)(T S A = 2pi r (r + h)`

Explanation:

`"Lateral Surface Area of a cylinder " L S A = 2 pi r h`

`"Base Area of the cylinder " A = pi r^2, " Area of Top & Bottom Circles"`

`"Total Surface Area of cylinder " T S A = 2 * A + L S A`

`T S A = 2 pi r^2 + 2 pi r h`

`color(brown)(T S A = 2pi r (r + h)`
