To convert area into circumference, take the two formulas for circles--circumference and area:
C=2pi*r
A=pi*r^2
Now, isolate the common variable (r) in the second equation.
r=sqrt(A/pi)
Now you can substitute this in for "r" in the first equation to find circumference
C=2pi*sqrt(A/pi)
C=2pi*sqrt(36pi/pi) pi cancels out
C=2pi*sqrt(36)
C=2pi*6
C=12pi

What is the circumference of a 36 circle?
The circumference of a 36 circle is: 113.1 (diameter x pi = circumference).
How is pi in relation to a circle?
Pi is related to the area and the circumference of the circle. The area is Pi multiplied by the radius of the circle squared and the circumference is Pi times the diameter of the circle. if you're wondering how it works, pi is the area of a circle with radius of 1 (unit), and the circumference of a circle with a radius of ½ (unit).
If a circle has a diameter of 36 what is the circumference?
pi x diameter gives you the circumference. pi x 36 = ? I don't have my calculator on me.
What is the circumference and area when radius 9in and d 7.3?
Circumference of a circle = 2*pi*radius or pi*diameter Area of a circle = pi*radius2
Area of a circle with a 12 inch circumference?
The circumference of a circle is given by Circumference = pi x diameter. The area of a circle is given by Area = pi/4 x diameter2. Thus for a circle with circumference c = 12 in. The area will equal a = 11.459 in2.
