-- Slice it down one side and flatten it out. -- Now you have a rectangle. You only have to find the area of a rectangle. -- The area of a rectangle is (length) times (width). -- The length of the rectangle used to be the length of the cylinder. -- The width of the rectangle used to be the circumference of the cylinder's round ends, while it was still rolled up.
Divide the surface area by the circumference of the circle, which is a product of the diameter x Pi. Essentially, an unrolled cylinder is a rectangle.
find the circumference of the circle and multiply it by the height of the cylinder
you divide the surface area by the circumference.
in order to find the area of a rectangle you must multiply the base of the rectangle by its height. This is also the same for most polygons

The length of a rectangle is twice its width. If the perimeter of the rectangle is , find its area.
find the circumference of the circle and multiply it by the height of the cylinder
Area = circumference squared... You do circumference divided by 4,... and then divide that by Pi.
the length of a rectangle is 5 more then the width. Find the perimeter and the area of the rectangle
find the perimeter and area of a rectangle that is 15cm long and 5cm wide
in order to find area of rectangle=(len*bred)
you divide the surface area by the circumference.
The circumference is: 32.1
in order to find the area of a rectangle you must multiply the base of the rectangle by its height. This is also the same for most polygons
First of all, find the area of the circle on top of the cylinder, using the formula... pi x radius^2 ... Multiply that by two because there are two circles on the cylinder. Then find the area of the rest of the cylinder, which is basically a rectangle. So, get the height, and multiply it by the circumference of the circle (also the length of one side of the rectangle) using the formula ... pi x diameter ...
