I would presume you would like to find the volume of the cylinder. :)
Given the base area of cylinder is 169pie ft.^2.
The base area of cylinder is a circle, which has a formula of pie × radius^2. 169pie = pie × radius^2 {Divide both sides of equation by pie} 169 = radius^2 radius^2 = 169 {Make radius the subject of equation} radius = +- (square root)169 {Reject the negative value and retain positive value, since radius can only be positive} radius = 13 ft.
The height of the cylinder is twice the radius, so the height will be: Height = radius × 2 = 13 × 2 = 26 ft.
The volume of cylinder has the formula of: Volume of cylinder = base area × height = pie × radius^2 × height = pie × 13^2 × 26 = 169 × 26 × pie = 4394pie ft. cm^3
Hope this helps! :)
P.s. If your question was not to find the area of cylinder, feel free to let me know! :)
