<span>We have to find the volume of a cylinder made by rotating a rectangle. When a rectangle with a width of 5 feet and a length of 8 feet rotates it makes a cylinder with a radius: r = 5 ft and a height h = 8 ft. The volume of a cylinder: V = r^2 * Pi *h ; V = 5^2 * 3.14 * 8; V = 25 * 3.14 * 8; Answer: Volume of a cylinder is V = 628 ft^2. </span>
The correct answer is (4, 90)
