i'm assuming the total base is the diameter of the bottom and the hypotenuse is the dimensions of the area between the fringe of the bottom and the right aspect. making use of the pythagorean theorem, you ought to locate the right of the cone to be 15 because 8^2 + x^2 = 17^2 (8 is the radius, a million/2 of the diameter). The formula for the quantity of a cone is a million/3(pi)(radius^2)(correct). So: V= a million/3 (pi) (8^2) (15) which may be 320 x Pi or about 1005.3094.........

V = 1/3 X pi X r X h
The formula reads, "The volume of a cone is equal to 1/3 times pi times the radius of the base squared, times the height."

The volume of a cone is equal to a third times the area of the circle at the base times the perpendicular height of the cone:
V = 1/3 π(r^2)h
Be sure that you use the perpendicular height when using this formula. In exam questions for instance, you may be given the slant height instead.
If you are given the slant height, you can use Pythagoras' Theorem to find the perpendicular height.

The volume of a cone is 1/3(Area of Base)(height) = 1/3(¶r2)(height).

volume of cone = 1/3 * area of the circular base * height of cone
= 1/3 * 3.14 * r^2 * h
where r is the radius of the base and h is the height of the cone.
this formula is valid only for right circular cone.

The volume of an conical structure is 1/3 the volume of the corresponding cylinder.
So, for a circular cylinder with radius r and height h, we get (1/3)pi*r^2*h.
For a pyramid with square base of sidelength x and height h, we get (1/3)x^2*h.
