If the radius of a circle is doubled, the area of the circle is quadrupled.
area of a circle = 2(pi)(radius)^2
when r = 2, area = 8pi
when r = 4, area = 32pi
you can see that the area is quadrupled

<h3>Draw a straight line through (0,0) and (3,5) to graph</h3>

The equation of this line is y = (5/3)x
