How to find surface area & volume Of A Cylinder?

Volume: pi*r^2*h

Surface Area:2pi*r^2+2pi*r*h

r=radius

h=height

Volume & Surface Area of Right Circular Cylinder :

V = Pi x r^2 x H

A = (2 x Pi x r x H) + (2 x Pi x r^2)

where :

V = volume

r = radius

H = height

A = total surface area

The SA of the cylinder part is equal to 2.pi.r.h (ie the circumference by the height of the cylinder). If you need to get the SA of the circles at the top and bottom or the cylinder you need to add 2.pi.r^2

ie SA = 2.pi.r^2 + 2.pi.r.h

The volume is equal to the area of the x-sectional circle by the height of the cylinder:

ie Vol = pi.r^2.h

In the era before calculators we all used a small book called "Mathematical Tables from Handbook of Chemistry and Physics". This small volume was required for it's log tables but it also has the formula that you requested along with a lot of other basic information. I recommend that you find a copy.

area:

Pir2 (pi times radius squared) times the height of the cylinder

surface area:

pi x diameter x the height (to find the body) + pir2 x 2 (to find the cross section)

The volume of a cylinder:

V = (4/3)*pi*r^3

The area of a cylinder:

A = 4*pi*r^2

cylinder

V = πr²h

A = 2πr² + 2πrh = 2πr(r+h)

r is radius

h is height or length
