Question

Find the circumference of the circle radio 3.5 cm

Answer 1

Answer:

21.98

Step-by-step explanation:

c=$\pi$2(3.5)

Answer 2

Answer: The circumference is 21.98

Step-by-step explanation:

I’m assuming instead of radio, you meant radius!

The equation for circumference of a circle is:

C = 2πr (Circumference equals two times pi times the radius)

You already know that pi ≈ 3.14, and that your radius is 3.5, so now we substrate he numbers into the equation.

C = 2 (3.14) (3.5)

C = 6.28 (3.5)

C = 21.98

Therefore, the circumference is 21.98

Hope this helps! :)
