A sector with radius of 15 and center angle of 216 ° is rolled into the side of a cone, and the height and volume of the cone are calculated

A sector with radius of 15 and center angle of 216 ° is rolled into the side of a cone, and the height and volume of the cone are calculated

The base circumference of the cone is 2 * π * 15 * 216 / 360 = 18 π
Base radius of cone = 9
Bus length of cone = 15
Height of cone = √ (15 & sup2; - 9 & sup2;) = 12
The volume of cone = π * 9 & sup2; * 12 / 3 = 324 π≈ 1017.36
