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.
Given; r = 5.25 m, h = 3 m
Volume of cone = 1/3 π r2h
= (1/3) X (22/7) X (5.25) X 3
= 50.625 cubic m
