Question 336522: if the radius of a circle is increased by 50%, what will be the percent increase in the circumference of the circle?

Let the radius=1
Then the diameter=2 and the circumference = 2pi
.
If the radius is increased by 50% then it is 1.5 and the circumference=3pi
3pi/2pi=3/2, an increase of 50%
