<span>The area of wall that will be painted in one roll would be equal to the curved surface area of the roller. Therefore, the curved surface area of roller= 2*pie*radius*height
Given: pie=3
So, Curved Surface Area of the roller=2*3*5*13 sq. in.
= 390 sq.in
Therefore, Area of the wall painted in one roll is equal to 390 sq.in.
While Area of the wall painted in 3 rolls will be (390*3) or 1170 sq.in</span>
