A sphere has a surface area of 2464 cm². If the radius of this sphere is increased to twice its original length, what will be the surface area of the new sphere?

Explanation

The surface area of a sphere is proportional to the square of its radius. Doubling the radius increases the surface area by a factor of 2² = 4. Therefore, the new surface area is 4 × 2464 cm² = 9856 cm².
