The area of circle if its curcumference is 14?

Answer 1

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
