Which explanation can be used to derive the formula for the circumference of a circle? 1. find the length of the diameter and double this amount. subtract it from the length of the circumference. set an equation to show the difference equaling the ratio between a circumference and radius. then rearrange the equation to solve for the circumference. 2. find the length of the radius. then find the circumference. use the square of the radius to set up an equation showing the relationship that the square of the radius equals the π times circumference. then rearrange the equation to equal the circumference. 3. find the length of the radius and the area of the circle. divide the area by the radius to get a quotient of π . write an equation showing the area of a circle equals this quotient times the radius. then substitute the area for 3 times the circumference and rearrange the equation to equal the circumference. 4. find the length of the diameter and the length of the circumference of the circle. divide the length of the circumference by the length of the diameter. set up an equation showing the ratio of the circumference to the diameter equal to π . then rearrange the equation by solving it for the circumference. substitute 2 times the radius for the diameter.

Pi is defined as the ratio of the circumference of a circle to the diameter of that circle. which of the following correctly explains why the formula for the circumference of a circle is 2 pi r? a. two times pi equals the distance from one side of the circle to the other. when you multiply around the circle, or the circumference. b. pi times r equals the diameter of the circle. the diameter is a half circle, so when you multiply it by 2, you get the distance around the entire circle, or the circumference. c. two times r equals the diameter of the circle. pi is needed for all circle formulas, so you multiply by pi since you are finding the circumference. d. two times r equals the diameter of the circle. pi equals the circumference divided by the diameter. when you multiply, the diameter is in both the numerator and the denominator, which cancels out, leaving the circumference.
