Tonia is in charge of renting tables for her sister's birthday party. The supply company has only round tables
Below shows the size of the tablecloths Tonia must use.
Size A Size B Size C
C 188.4 in. C = 150.72 in. C = 113.04 in
Part 1: Tonia can determine the size of the tables needed to fit her tablecloths by determining the radius of the tables needed. Rewrite the circumference formula, solving for r. Show and/or explain your work.

The circumference formula is C = 2πr. Solve for r by isolating r:
C = 2πr
=> r = C / (2π).
(Equivalently: C = πd so d = C/π and r = d/2 = C/(2π).)
Using r = C/(2π) and π ≈ 3.14159, the radii for the given cloths are:
- Size A: r = 188.4/(2π) ≈ 29.985 in
- Size B: r = 150.72/(2π) ≈ 23.988 in
- Size C: r = 113.04/(2π) ≈ 17.991 in
C = 2πr
=> r = C / (2π).
