Question

20 POINTS!!! I GIVE BRAINLIEST PLEASE HELP!!!!A circle with a circumference of approximately 15.71 inches drawn inside a square, just touching the sides of the square. Explain how to determine the length of one side of the square.

Answer 1

answer:

5.002 inches

step-by-step explanation:

• find the diameter of the circle
• the diameter is the side length of the square since the sides of it are touching the circle

c = 2πr

• c stands for circumference
• π stands for pi (or 3.14)
• r stands for radius

- plug in the values given to find the diameter

c = 2πr

15.71 = 2(3.14)r

15.71 = 6.28r

r = 2.501 (rounded or estimated)

• now that we have the radius, we can find the diameter by multiplying by 2, since diameter is two times bigger than the radius

diameter = 5.002 (estimated)

• now, that will be the side length because the diameter = the side length
