Question

if the radius of a circle os increased by 6%,then the area increased by:

Answer 1

We know that Area of circle = pi r * r cm^2

                       Given Area = pi * (1.6) * r * r cm^2

Increase in area = pi * r * r (1.6 - 1) 

                           = 0.1236

So, Area is increased by 12.36%.


Hope this helps!
