A heap of wheat is in the form of a cone whose diameter is 10.5 m and height is 3 m. Find its volume. The heap is to be covered by canvas to protect it from rain. Find the area of the canvas required
Radius (r) = 5.25 m
Height (h) = 3 m
Volume = r2h
= * * 5.25 * 5.25 * 3
= 86.625 m3
Area of canvas = CSA of cone
= πrl
= πr
= * 5.25 *
= 99.825 m2
