Area and Volume
A right circular cone is cut off at the middle of its
height and parallel to the base. Call the smaller cone so
formed A and the remaining part B, then :
(a) Vol. A < Vol. B (b) Vol. A = Vol. B
(c) Vol. A > Vol. B (d) Vol. A =
1/2(Vol.B)

-
- Let height = 2h and radius = 2r
Vol of whole cone V = (1/3)pi*(2r)^2*(2h) = 8/3* pi * r^2 * h
Now Vol A (Va)= 1/3*pi*r^2*h
Vol B = V - Va = 7/3 * pi* r^2 * h - 9 years agoHelpfull: Yes(0) No(1)
