To solve the problem above, we will be using the equation in solving the surface area of a cylinder which goes. A = 2pi r^2 + 2pi r h, A is for the surface area, pi is 3.1416; h is the height and r is the radius. Basing on this formula the radius will be 0.3982 ft both top and bottom.

For the statement to be true, 'a' and 'b' must be equal
*First expand the binomial using FOIL, then set it equal to whats given "2abi".
Then you can find the relationship between a and b.
