Answer:
Hey!
Your answer is 11cm!
Step-by-step explanation:
So to get the radius from the Circumference we need both the Circumference and the value of pi...3.14
Radius = ... (that's the formula)
<u>WE SUBSTITUTE IN:</u>
<u>Radius =</u> 69.1/2 x 3.14
69.1/6.28
This equals = 10.99760656765
BUT 11cm when you round it to the next whole number or 2sf
