Re: Equilateral cylinder problem. Given radius, find...

For an equilateral cylinder, the diameter is equal to the height. The radius is given as 6 m, thus the diameter is 2r = 12 m. Then:

a) height = 2r = 2(6 m) = 12 m.

b) The total surface S area is:



Using the given data:



c) The volume V is:



Using the given data:
