you find the surface area of a circle by first finding the area of the circles/ two ends.
you do this by multiplying the diameter by pi then multiply by two, that is both ends put together
then you find the area of the flat part by finding out the circumference of the circle ends, then multiply that by the height of the cylinder.
circumference= pi times the diameter
then add all your calculation together, and you have the surface area of your cylinder :)

It depends on the surface area of what!
A circle.
It is the surface area
The diameter of a circle is 56 cm. What is the circumference of the circle? Use 22/7 to approximate for pi.
To find the area of the top surface of the can, we need to calculate the area of a circle. The formula for the area of a circle is A = πr^2, where A is the area and r is the radius. Since the diameter of the can is 8 cm, the radius is half of that, which is 4 cm. Plugging in the values, we get A = π(4 cm)^2 = 16π cm^2, which is approximately 50.27 cm^2.
