What is the volume of a cylindrical ring if we know the diameter of the revolving circle is 4 ft. and the length of the center line is 65 ft.? A. 567.94 ft.3 B. 624.33 ft.3 C. 816.82 ft.3 D. 488.20 ft.3
As we know that, volume of a cylinder is given by expression, 3.142 * height *(radius)^2
As all the units are in feet
i.e. 3.142 * 65 * 4 = 816.92
Hence, correct answer is C
