Concept: Use the

formula to calculate the curved surface area of a sphere to solve the problem.The surface area filled by the cylinder's bases and curving surface may be calculated using the cylinder's surface area formula. We can express both the total surface area and the curved surface area of a cylinder since it has a curved surface.
Given,
CSA of sphere =

To find the radius,
Therefore, let's utilize the sphere's curved surface area formula to solve this. The formula provides the sphere's curved surface area.
CSA=
