Question

To find the surface area of a right circular cylinder
experimentally.​

Answer 1

Answer:

Observations and Calculations

So, the curved surface area of the cylinder = 2πrh. Also, the area of each circular sheet = πr². the total area of the top and bottom surfaces of the cylinder = 2 x πr²=2πr². Hence, the total surface area of the cylinder = 2πrh + 2πr²=2πr(h+r).
