Total amount of concrete used =Volume of 50 cones.
First, we calculate the volume of one such cone.
Radius(r)= d/2 =35/2 cm =0.35/2 m
Height(h)= 1 m.
Volume of 1 cone(V)=(1/3)π(r^2)h
=(1/3)(22/7)((0.35/2)×(0.35/2))(1) cubic meter
=(11×0.35×0.5)/6 cubic meter
Volume of 50 such cones =50×V
=50×(11×0.35×0.5)/6 m^3
=16.04167 m^3
≈16.04 m^3
Hope this helps. For more clarification or discussion please comment or message.
