Question 776951: If the radius of a circle is r cm, what is the area of the circle? If the radius is increased to 2r cm, what is the area of the circle? Answer by Cromlix(4381) (Show Source):
You can put this solution on YOUR website! If the radius of a circle is 'r'
The area = Pi * r^2
If the radius is increased to '2r'
The area = Pi*4r^2.
Hope this helps.
