➷ 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 (r^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 =
The length of the rectangle would be the height of the cylinder
We can use this:
This would calculate the surface area as it would find the area of the rectangle plus the area of the two circles.
