To calculate the circumference multiply the radius by 2 to get the diameter. Multiply the result by π, or 3.14 for an estimation.
3.22x 2 = 6.44
6.44x π= 20.23185668911827
rounded to the nearest ten: 20.2
To change radians to degrees we *by 57.3.56*57.3=3208.8/60=53.48

Answer:
Water boils at 212° on the Fahrenheit scale, so a measurement of 132° on a Fahrenheit scale is legitimate for hot (but non-boiling) water.

Answer:
Step-by-step explanation:
Greek students will represent p1 (proportion 1)
Non-Greek students will represent p2
If we were to conduct a hypothesis test for this data, we would use a test for the difference of 2 proportions. The hypothesis for this test would be as follows...
H0: p1 - p2 = 0
Ha: p1 - p2 > 0
The reason the alternate hypothesis is greater than 0 is because the question claims that the proportion of greek students (p1) is greater than the proportion of non-greek students (p2). So p2 is smaller than p1. We are subtracting a smaller number from a larger number. That will always result in a positive number.
