pi * 225/4
Radius is 15/2
pi r2 = pi * (15/2)2 = pi * 225/4
diameter = 30 units area = 225*pi square units
diameter is 15 area of the circle is... 706.5 if im not mistaken
The area is 176.714 units2
706.5cm
The circle's area is 176.71 square feet.
Area = 176.71 feet2
The area of the circle: pi*15*15 = 225*pi square measurements
176.7 cm2
176.71 square inches.
Radius is half of the diameter
Using 3.14 as Pi the area of circle is: 176.625
The formula for area of circle is: A=pi*r2 r=d/2 =>r=15/2=7.5 =>A=pi*(7.5)2 =>A=3.14*56.25 = about 176.625 square units
