+1431 The circular sector below is rolled to form a cone. Find the volume of the cone.
+129845 Circumference of cone base = ( 2 pi ) (36) (150 / 360) = 30 pi
Radius of cone = 30 pi / ( 2 pi ) = 15 = r
Height of cone = sqrt [ 36^2 - 15^2 ] = sqrt [ 1071 ] = 3sqrt (119)
Volume of cone = (1/3) pi r^2 * h = (1/3) pi * (15 )^2 * 3 sqrt (119) =
225 sqrt (119) pi ≈ 7710.9
