Given
A circular ring
Required
The length
Let
the radius of the ring
The length is calculated by calculating the circumference of the ring.
This is calculated using:
or
Where
diameter
and 
The answer is 21.2 ft²
To do this we need to calculate the volume of the cylinder shaped drum.The volume (V) of the cylinder with height h and radius r is:V = π r² h
We have:π = 3.14r = 1.5 fth = 3 ft
Therefore:V = π r² hV = 3.14 * (1.5 ft)² * 3 ftV = 21.2 ft²
here you go
