Question

The radius of a sphere increases by 25% find the persentage increase in its surface area​

Answer 1

Let the original radius of the sphere be r units. So, original volume of the sphere will be 4πr³/3 and original surface area will be 4πr². If the radius of the sphere is increased by 25% it means that the new radius will be: r + 25% of r = 125r/100.
