Question

a heap of rice is in the form of a cone of base diameter is 24 M and height 3.5 M find the volume of the rice how much can loss cloth is required to just cover the hip

Answer 1

cone volume =1/3×pi×r×r×h
=1/3×22/7×12×12×35/10
=22/7×4×6×7
=22×4×6
=528m

loss cloth amount=2×pi×r
=2×22/7×35/10
=22m
