Can someone help me Thank you

Okay. Let’s begin!
I order to solve this problem we must u do it and redo it. We have to find the diameter and the radius
Step one: 15 divided by 3.14 (PI) which is 4.77707006. That’s the diameter. Now divide that by two for the radius which is 2.38853503
Step two: find the area
Formula: PI(r)^2
Step three: solve for the area
3.14(2.38853503)^2
Step four: answer
Your answer is.....
17.9140127. Or if ur rounding:
18.
I hope this helped!
