Question

explain total surface and volume of a cylinder with formula and example​

Answer 1

TSA:-

The Surface Area of Cylinder = Curved Surface + Area of Circular bases

S.A. (in terms of π) = 2πr (h + r) sq.unit

Where, π (Pi) = 3.142 or = 22/7

r ,is the radius of the cylinder

h, height of the cylinder

TSA = 2π × r × h + 2πr2= 2πr (h + r) Square units.

Volume:-

the cylinder’s volume of base radius ‘r’, and height ‘h’ = (area of base) × height of the cylinder

Since the base is the circle, it can be written as

Volume = πr2 × h

Therefore, the volume of a cylinder = πr2h cubic units.
