Question

What is the diameter of a circle that has a circumference of 56.52 feet? D=_________

Answer 1

We know, Diameter = Circumference / π
d = 56.52 / 3.14
d = 18

In short, Your Answer would be 18 Feet

Hope this helps!

Answer 2

  Equation for circumference of a circle is = 2*pi*r 
56.52=2*pi*r 
56.52/2*pi=r 
r= 9 

Equation for area of a circle = pi*r^2 
A= pi * (9)^2 
A= 81pi or 254.34 hope it helps ;p
