Consider a circle whose size can vary. The circumference of the circle is always \( 2 \pi \) times as large as its radius. Let \( r \) represent 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 \( 37.6991 \) feet.
