I would be glad to help you! I will solve through 3 to get you started.
This is a very important concept, so it would be helpful if you learn it on your own.
C= 2* pi* r
1. The radius is 5 cm. 5 cm represents r in the equation.
C= 2* 3.14 (or pi)* 5
Multiply it by using a calculator.
My answer was 31.4.
Let's try the second one.
2. The diameter is 9. Have of the diameter is the radius.
9/2= 4.5
Plug it into the equation.
C= 2*3.14*4.5
I got 28.26
One more.
Plug it into the equation.
C= 2*3.14*5.6
35.17 was my answer.
Make sure to add the end signs to you answer, ft, cm, meter, etc.
Let me know if you need more help.
Brainliest answer is always appreciated.

Answer:
Sonji is 0.5 miles far from the finish line
Step-by-step explanation:
Data provided in the question:
Distance between the Sonji and the finish line = 0.4 miles
Distance run by Sonji back = one tenth of a mile
i.e = 
miles = 0.1 miles
Hence,
The total distance of Sonji from the finish line will be
= Distance between the Sonji and the finish line + Distance run by Sonji back
= 0.4 miles + 0.1 miles
= 0.5 miles
Hence,
Sonji is 0.5 miles far from the finish line
