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.
30+0.10x
340/0.10=34
34+30=64
64 dollars, I think
After 2 hours she wrote 3 entries.
after 4 hours she wrote 6 entries.
This means that for same period she is writing same number of entries which means her "writing speed" is constant.
that means that graph is linear function (straight line).
slope we calculate by putting coordinates of y and x of any dot on that line. we can use one of those given by text of task. (in 2 hours she wrote 3 entries)
y = k*x
k = y/x
k = 1.5
