The formula for radius of a cone is radius is equals to square root of volume times 3, which is divided by height times pie. Pie refers to 22 divided by 7.

sqrt( (R-r)^2 + h^2)where:R = radius of larger endr = radius of smaller endh = height of truncated cone
volume=pi*radius squared*height/3, where radius is the radius of the cylinder (and will be the radius of the base of the cone),and height is the lenth of the cylinder.
The slant height of a cone is given by the formula , 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.It is trivial to see why this formula holds true. If a right triangle is inscribed inside the cone, with one leg of the triangle being the line segment from the center of the circle to its radius, and the second leg of the triangle being from the apex of the cone to the center of the circle, then one leg will have length h, another leg will have length r, and by the Pythagorean Thereon, r2 + h2 = d2, and gives the length of the circle to the apex of the cone.
False. The surface area formula for a right cone is not the same as the surface area formula for an oblique cone.
For a circular cone: sqrt( (R-r)^2 + h^2) where: R = radius of larger end r = radius of smaller end h = height of truncated cone For cones of other shapes the average of the area of the top and bottom surfaces times the height (perpendicular to the plane of the top/bottom)
