. Write the formula to find the total surface area of a cylinder
The TSA of a cylinder is often defined because the total space is covered by the flat surface of the bases of the cylinder and its curved surface.
The total area of the cylinder has two components-a curved area and two flat surfaces areas.
The formula of total area of cylinder:
There are two circular bases
A = 2πr
One curved surface area i.e. 2πrh.
Total surface area = two circular bases in One curved surface area
=2πr2 + 2πrh
=2πr(h+ r) cm2
The formula of the total surface area of a cylinder is 2πr(h+ r) cm2
