Answer:
2.905
Step-by-step explanation:
The equation for circumference is circumference=2(pi)radius. So far, our equation (with the information plugged in) looks like this: 18.25=2(pi)radius. We can now solve this because there is only one unknown variable (the radius). Getting the radius by itself makes the equation look like this: 18.25 divided by (2 times pi)= radius. Plug it into your calculator and you get 2.904577711, which I would round to 2.905.
