What is the circumference of Circle O?

Answer:
[tex]14\pi[/tex]
Step-by-step explanation:
The formula for finding the circumference of a circle is 2 times pi times the radius.
Looking at the picture, we can see that the radius of the circle is 7 cm. Plugging that into the formula gives:
2*[tex]\pi[/tex]*7 = 14[tex]\pi[/tex]
Answer: 14π cm or 43.98 cm.
Step-by-step explanation: To find circumference, one must use the equation c = 2πr (c = circumference and r = radius). Plugging in the values, we get 2πr = 2*π*7 which = 14π or if you want it rounded: 43.98 cm.
