Question 107743: Manipulate literal equations.
38. Use the formula C=2πr to find r of a circle with a 100 meter circumference. Use 3.14 as an approximation for π.
39. Use the formula C=2πr to find r of a circle with a 10 meter circumference. Use 3.14 as an approximation for π.
40. Use the formula C=2πr to find r of a circle with a 28 inch circumference. Use 3.14 as an approximation for π.

You can put this solution on YOUR website!
C=2PIR
100=2*3.14*R
100=6.28R
R=100/6.28
R=15.92 METERS IS THE ANSWER FOR THE RADIUS.
