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.
Class of students - number of students that are boys = numbers of students that are girls
30 - 13 = 17
To change the number of students that are girls into percentage...
17/1 * 1/100 = 17/100
17/100 in a % form = 17%
The percentage of girls in the class is 17%
This is because minus times minus is equals plus so the sign must change
