➷ As there would be 2 circles, you'd need to find the area of a circle and then multiply it by 2

To start with, we can use this:

2 (\pir^2)

^^ This represents the surface area of the two circles

A cylinder also has a rectangle which is rolled to form the shape

As we know, the formula of a rectangles area is length x width

The width of the rectangle would be equal to the circumference of a circle

circumference of circle = \pi d

The length of the rectangle would be the height of the cylinder

We can use this:

(\pi d * h) + 2(\pi r^2)

This would calculate the surface area as it would find the area of the rectangle plus the area of the two circles.

➶ Hope This Helps You!

➶ Good Luck (:

➶ Have A Great Day ^-^
