area of the base =circumference
2pir=156
2×22/7×r=156
r=156×7/2×22
r=24.8
Vol of cone =1/3 pi r ^2h
1/3×22/7×24.8×24.8×8
5154.6

v of cone = 1/3 pi*r sq*h
but area of base of cone = pi*r sq
this implies volume of cone = 1/3 area of base*h
= 1/3*156*8
= 416 cm sq
but area of base of cone = pi*r sq
this implies volume of cone = 1/3 area of base*h
= 1/3*156*8
= 416 cm sq
