Carpenters often have to find the distance around the outside of a circle. The distance around a circle is its circumference. To find the circumference of a circle, multiply the diameter of the circle times pi. The value of pi is approximately 3.1416. Pi is written in equations as π.
Since the diameter of a circle is equal to twice its radius, another way to find the circumference is to use the formula, 2πr, or two times pi times the radius.
For each problem, round the answer to the nearest hundredth.
