Which explanation can be used to derive the formula for the circumference of a circle? Will give brainliest!
A) Find the length of the diameter and double this length. Multiply this length by π and set equal the to the circumference. Substitute the diameter for 2 times radius.
B) Find the difference between the length of the circumference and diameter. Set up an equation showing the relationship of the circumference to diameter to the difference. Rearrange the equation to solve for the circumference. Substitute the diameter with 2 times the radius.
C) Find the ratio of the diameter to the area of the circle. Use this ratio to set up an equation to show this ratio equaling π. Substitute the area with 3 times the circumference. Then rearrange the equation to equal to the circumference.
D) First find the relationship of the circumference to its diameter by finding that the length of the diameter wraps around the length of the circumference approximately π times. Use this relationship to write an equation showing the ratio of circumference to diameter equaling π . Then rearrange the equation to solve for the circumference. Substitute the diameter for 2 times the radius.
