PT 1
the circumference of a circle is always pi times the diameter. The diameter is 2 times the radius, because diameter is all the way across the circle, whereas radius is from the center of the circle to the edge. Anyways, if the radius is 6, multiply it by 2 and you get 12, so 3.14 times 12 is 37.68, which is the answer.
PT 2
diameter=9 cm. So, just do 9 times 3.14. (diameter times pi = circumference.)
(2*radius times pi = circumference.)
9 times 3.14 is 28.26

Question:
You are ordering short-sleeve shirts (x) for $10 and long-sleeve shirts (y) for $15. Your budget is $300. Write the equation and find the intercepts.
Interpret their meaning.
Answer:
The x-intercept shows that you can buy 30 short-sleeve shirts and 0 long-sleeve shirts.
The y-intercept shows that you can buy 20 long-sleeve shirts and 0 short-sleeve shirts.
Step-by-step explanation:
Given
$10 per short sleeve
$15 per long sleeve
Budget = $300
The above can be represented as:
Total Cost of Short Sleeve + Total Cost of Long Sleeve = Budget
i.e.


To solve for the y intercept, we set x to 0


Divide through by 15

<em>This implies that, you can buy 0 short sleeves and 20 long sleeves</em>
To solve for the x intercept, we set y to 0


Divide through by 10

<em>This implies that, you can buy 0 long sleeves and 30 short sleeves</em>
