Answer:
19.72 cm²
Step-by-step explanation:
A solid circular cylinder has a base radius 5 cm and a height 12.5 cm.
The volume of cylinder is given by :

When r = 5.05, new volum becomes,

Increase in area = 1000.97 - 981.25 = 19.72 cm²
So, the increase in surface area of the cylinder is equal to 19.72 cm².
