Help ASAP read my profile picture so you can understand the desperation I’m feeling (if you help me with this you could probably do my last question too!!)

Answer 1

Answer:

Diameter = 23  Radius = 11.5

Step-by-step explanation:

Divide the circumference by π, or 3.14 for an estimation. The result is the circle's diameter.

72.22 ÷ 3.24 = 23

diameter = 23

Divide the diameter by 2.

23 ÷ 2 = 11.5

There you go, you found the circle's radius
