Answer:

If the radius of the sphere is increased by 25% it means that the new radius will be: r + 25% of r = 125r/100. So, now we can calculate the volume and surface area of new sphere by taking new radius as 125r/100. So, the new volume = 4π(125/100r)³/3 and the new surface area = 4π(125r/100)².
