the circumference of a circle is 18n inches. Find its radius and area The radius of the circle is Answer by Cromlix(4381) (Show Source):
You can put this solution on YOUR website! The circumference of a circle = Pi*diameter
I will assume that 18n is really 18 Pi
If so the radius = 9 inches (Radius = Diameter/2)
Area of circle = Pi * r^2
Area of circle = Pi * 9^2
Area of circle = Pi * 81
area = 254.5 inches^2
Hope this helps.
