PLEASE HELP ASAP Assignment: circumference investigation

Part 1: 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 the circles have a radius of one. Then, calculate the ratio of the approximate circumference to the diameter.

B. Now, assume that all of these circles have a radius of two. Then, calculate the ratio of a proximate circumference to the diameter.

  the correct choice is marked

step-by-step explanation:

the first two graphs show multiple turning points. the last graphs matches the description in every detail.

x + y = 90 5x – 10y = 90 90 – 10y = 5x 90 + 10y = 5x

step-by-step explanation:

last month maria hiked the 5-mile mountain trail a number of times and she hiked the 10-mile canal trail several times. let x represent the number of times she hiked the 5-mile trail, and let y represent the number of times she hiked the 10-mile trail. if she hiked a total of 90 miles, which equation can be used to find the number of times maria hiked each trail? x + y = 90 5x – 10y = 90 90 – 10y = 5x 90 + 10y = 5x
