Answer:
12.56
Step-by-step explanation:
The formula for circumference is either πr² πd. Thats basically just multiplying. All you have to do is take the the diameter and multiply it times pi and you get the answer. In some cases they want you to use the radius; radius is diameter divided by 2. Example is if 4 is the diameter 2 is the radius. For this one i did 4 times 3.14(pi).
I hope that helps!

Step-by-step explanation:
Answer:the answer for part A is SAS.
Step-by-step explanation:
We already know that side PQ is the same length for both the triangles. We were then given the information that sides PM and PN were equal. So now we already have two sides that are the same. Then we were given the information that angle MPQ and angle NPQ were also equal. So now we have two sides and an angle that are equal. This is how we got SAS (side angle side). I tried my best to explain. I added a photo so you could see what I was trying to explain. Hopefully this helped!
Answer:
<u><em>Answer is below</em></u>
Step-by-step explanation:
<u><em> Divide both sides by 3.</em></u>
It’s pi times the diameter which is 7 so it would be 22
