Question

A cone of height h cm and base radius r cm is reshaped into a sphere. Then, which of the following is always correct?

• A. Volume of cone = Volume of Sphere
• B. Surface Area of Cone = Surface Area of Sphere
• C. Can’t Say anything about the volume or surface area relation
• D. Radius of sphere = Radius of base of cone + Height of cone

Answer 1

The correct option is A

Volume of cone = Volume of Sphere

Volume of an object does not change when it is melted and reshaped to form another object .
Therefore ,Volume of the cone = Volume of the sphere.
