formula for circumference is :
C= pie (times) diameter
14= pie Diameter
14=3.14 diameter
so divide by pie on both sides to find the diameter
aprox: 4.456 = diameter
formula for area is :
a= pie radius ^2
so find the radius which is half the diameter
4.456/2 =2.228 = radius
square the radius
2.228^2= 4.964
times by pie
area= 15.597

The area of a circle that has a diameter of 14 inches is: 153.9 square inches.
Area of a circle = pi*radius squared
15.70 meters Circumference = diameter x pi 5 meters x 3.14 15.70 meters
Area = pi*142
Area = 153.9 inches2
