Area of curved surface of a solid sphere is equal to the curved surface area of a solid right circular cylinder. If the height and the length of diameter of the cylinder both 12 cm in length, then calculate the radius of the sphere.

A cube is inscribed in a sphere. A right circular cylinder is within the cube touching all the vertical faces. A right circular cone is insido tho cylinder. Their heights are same and the diameter of the cone is equal to that of the cylinder. Consider the following statements : 1. The surface area of the sphere is sqrt5 times the curved surface area of the cone. 2. The surface area of the cube is equal to the curved surface area of the cylinder. Which of the above statements is/are correct ?

Prove that the surface area of the sphere is assume as that of the lateral surface of a right circular cylinder, which just encloses the sphere.

A right circular cylinder circumscribes a sphere of radius r.Find the ratio of the surface area of the sphere to the curved surface area of the cylinder.
