You must know some information about the cone, volume and height.
V = (1/3) pi x r2 x h, so substitute those values in, rearrange and solve by taking square root at the end of the problem.

Volume of a cone = 1/3*pi*radius2*height To find the radius make it the subject of the above formula.
the formula is one thirdx pix radius squared
Radius of cone = 19/2 = 9.5 mm Volume = (1/3) PI r^2 h, where r is the radius and h is the height, We need to know the height of the cone to find its volume.
the slant height of a right circular cone is the distance from any point on the circle to the apex of the cone . The slant height of a cone is given by the formula ,√r2+h2 where r is the radius of the circle and h is the height from the center of the circle to the apex of the cone.
