The formula for circumference is 2 x Pi x R or Pi x D. The diameter is twice the radius, always. With the information I have provided, we can solve this.
Our radius is 7.
Multiply the radius by 2 to get the diameter.
7 x 2 = 14. Since you have requested for the answer to be in terms of Pi, I will assume you mean "14Pi" as your final answer. If not, I will multiply 14 by Pi to get our circumference.
3.14 x 14 = 43.96 cm^2
Your answers are:
14(Pi) cm^2
or (if completely done)
43.96 cm^2
The Area of a circle is PiR^2, or Pi x R x R. Our radius is 7, so to solve this, we need to: Multiply 7 by 7 and then multiply that product by 3.14. 7 x 7 = 49. 49 x 3.14 = 153.86 cm^2 Your area is 153.86 cm^2. Your circumference is 43.96cm^2. I hope this helps!
