Part I: Measuring Parts of a Circle
a. Help Dakota with her homework. Use diagrams of inscribed polygons to approximate the circumference of each circle. Assume that all of the circles have a radius of 1. Then, calculate the ratio of the approximate circumference to the diameter.

56.6

step-by-step explanation:

the ratio of the perimeters is equal to the scale.

the ratio of the areas is equal to the square of the scale.

34 / 20 = k

a / 19.6 = k²

substituting:

a / 19.6 = (34 / 20)²

a = 19.6 (34 / 20)²

a ≈ 56.6

don't report but were is the digram
