HELLO DEAR,
Volume of cone = 1/3 * pie * r * r * h
D = 9 m , r = 9 / 2 m
Volume = (1 / 3) * (22 / 7) * (9/2)*(9/2)*(3.5) = 74.25 m3
Just to cover , the heap, we need the CSAof cone
Slant height of cone = root [ r2 + h2 ] = root [ (9 / 2) * (9 / 2) + (3.5)*(3.5) ] = 5.7008 m
CSA= pie * r * l = (22 / 7) * (9/2) * (5.7008) = 80.6256 m
.I HOPE ITS HELP YOU DEAR,
THANKS
