Question

A sphere is put inside a hollow cone having base radius r. then find out the ratio between the radius of sphere and the hollow cone

Answer 1

The Radius will be Maximum when the triangle is equilateral triangle and the circle will be the incircle of the triangle.

Sphere whose radius = r,Volume of sphere = 4/3 πr cube 3.Surface area of sphere = 4πr square 2.If a sphere is placed inside a right circular cylinder so as to touch the top, base and the lateral surface of the cylinder. The height h is the distance from the apex to the circular base.Cones come in many sizes and shapes. I have a right circular cone of height h units and with radius m. The corresponding largest sphere has radius r. By examining the cross section, we can see similar right triangles.
