Volume of a cone with radius r and height h is equal to one-third the product of the height and the area of the base.
Vol = (1/3)*(Pi)*r^2*h
Vol = (1/3)*(Pi)*(7^2)*9
Vol = (1/3)*(Pi)*(49)*9
Vol = 147*Pi
Vol = 461.81cm^3, more or less

Volume of a cone =
Area of the base x Height x 1/3
(Ïr² x h x 1/3)
7² x Ï x 9 x 1/3
= 147Ï cm³

V = (1/3)pi.r^2.h
= (1/3) * pi * 7^2 * 9
= 461.814cm^3 (approx)

V = (1/3).Ï.r².h
V = (1/3) x Ï x 7² x 9 cm³
V = 461.8 cm³
