The circumference of a circle is equal to 2πr, where r is the radius. The radius is the distance from the center of the circle to a point on the outside of the circle.
To find the circumference you can <u>plug in the known information</u> and multiply. However, instead of using actual pi, we will use 3.14 because that is what the question says.
2 * 3.14 * 4.5 = 28.26
This means that the distance around the rug is 28.26 feet.
If you start with the balance being $2000, the monthly payment is $100 with the percentage rate being 1%. You would way 0.84 per month and if you multiply that by three months, you get $2.52.
