Answer:
21.07
Step-by-step explanation:
This problem is a 2-step process. First you have to find the distance between the two points on the circle, using the formula , which would give you the diameter. After the diameter is found, using the formula C=πd, the circumference can be found.
Using the points (1,7) and (-2,1), we can find the diameter of the circle by plugging it into the first equation.
d=\sqrt{((1--2)^2+(7-1)^2}
After plugging that into a calculator, we can find that the diameter is approximately equal to 6.71.
Now 6.71 can be plugged into the equation C=πd to find the circumference.
C=πd
C=π*6.71
<u>C≈21.07 units</u>

Answer:
(C * 9/5) + 32
Step-by-step explanation:
Basically, going from fahrenheit to celcius, you have to Deduct 32, then multiply by 5/9. So just reverse it, instead, you multiple it by the reciprocal, which is "9/5" then you add 32. Simple. :)
