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.

Greg has decreased his running time by 1/10 minute each of the last six weeks. Write an expression to represent the total change
Nastasia [14]

x is your starting running time. 1/10 of a minute is 6 seconds, so you can do x - 6(6). 6 times 6 = 36, so your answer is x - 36 seconds. 36 seconds.
