Answer:
2.3
Step-by-step explanation:
First off, you start with the circumference formula which is 2(pi)r. Since we know our circumference, we can create the equation solving for r. so we have 15=2(pi)r. Now in order to solve for r, we need to transfer everything to the other side, meaning dividing by 2(pi). So 15/2(pi)=2(pi)r/2(pi). Since we are using 3.14 for pi, 3.14*2 is 6.28. 15/6.28 which is about 2.388 So the radius of the circle is 2.3 (rounded to the nearest tenth)
