Nope. <just joking> ;)
Area is in square feet ft^2, volume is in cubit feet or ft^3.
A cylinder with a radius R (measured in feet)
and a height of H (measured in feet) has
Volume = 3.1415 x R x R x H (ft^3)
"two pi R squared times H"
Area of the cylinder side plus the 2 ends -
Area = the area of the 2 ends plus the area of the cylinder,
Area = 2 x (3.1415 x R x R) + H x (2 x 3.1415 x R) (ft^2)
You can reduce this monster to the following by factoring
to get the easier
Area = 6.283 x R x (R + H) (ft^2)
"R plus H times two pi R"
Area of the cylinder side without the ends -
Area = H x (2 x 3.1415 x R) (ft^2)
Area = 6.283 x R x H (ft^2)
"two pi R times H"
