(1)How much water can be held by a cylindrical tank with a radius of 12 feet and a height of 30 feet.
(2)The diameter of a frisbee is 12 inches, what is the area of the frisbee

V = pi r^2 h = pi (144)(30) = 13571.68026 ft^3

1) Use the formula I showed in my last post to you.
2)
Area = pi * r^2
I'll be glad to check your answers. 
area of one side is pi r^2 = pi(36) = 113.1 in^2 on the top
same on the bottom so
226.2 for both top and bottom.
