Sally designed a gold bracelet using 8 thin gold circles, arranged each circle has a radius of 2.5 what is the diameter and what is the length '5cm' of the chain

Diameter of the circle = 5.0 unit

The length of the chain = 40 units

Step-by-step explanation:

Given

Number of thin gold circles used for making bracelet is equal to 8

Radius of the circle = 2.5 units

Diameter of the circle = 2 * Radius of the circle

Diameter of the circle = 2 * 2.5 = 5.0 unit

The length of the chain = 8 * diameter = 8 * 5 = 40 units

answer;

the correct answer

just use google you beautiful person.

have a nice day < 3

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
