Question

write the formula for total surface area of a cylinder and explain the terms in it

Answer 1

Total surface are of a cylinder is
$2\pi \: rh(h + r)$
r - radius of the cylinder
h - height of the cylinder
$\pi = 22 \div 7$

Answer 2

Answer:

2 π r (h + r)

Step-by-step explanation:

Total Surface Area of a Cylinder is

Area of curved surface area of cylinder + Area of two circular ends.

2 π r h + 2 π r² = 2 π r (h + r)  

r = radius of the cylinder

h = height of the cylinder

Value of π = 22/7 or 3.14
