By adding the area of the top, bottom, and side will get the surface area of the cylinder.
We can use Heron's formula to find the area of a triangle with side lengths a, b, and c.
The surface area includes a curved surface area and two circular bases of the cylinder.
Curved Surface Area = 2πrh, use this fromula to find radius.
Use the formula to find the surface area.
The different formula of a cylinder
Use the Surface area formula of a rectangular prism
Surface area = 2lw+2lh+2wh Where l = Length of the prism w = Width of the prism h = Height of the prism
The surface area of the cylinder is equal to the sum of curved surface area and areas of of the circular bases.
Volume = πr^2h, use this formula to find radius.
