HELP QUICK!!!!

Answer 1

C=2πr

Explanation:

C =2πr is the formula to calculate circumference of a circle

Where

• C=Circumference
• r is radius
• π has Approx value 3.141

Answer 2

C = 2πr

Explanation:

The circumference of a circle is calculated by the formula here,

C is the circumference of the circle.

r is the radius of the circle.

π is 22/7 or 3.14.

In the given options π is not missing.

Therefore the formula that relates circumference and radius is C = 2πr.
