Consider a circle whose size can vary. The circumference of the circle is always 2π times as large as its radius. Let r represen
t the radius of the circle (in feet) and let C represent the circumference of the circle (in feet).
a. Write a formula that expresses C in terms of r.
b. Use your formula from part (a) to determine the circumference of a circle whose radius is 6 feet feet
c. Write a formula that expresses r in terms of C.
d. Use your formula from part (c) to determine the radius of a circle whose circumference is 37
