Circumference = 2 * PI * radius
circumference = 2 * PI * 12.6
If the central angle is 120°, then the arc will be exactly one third of the circumference.
arc length = (2 * PI * 12.6) / 3
arc length = 8.4 PI
Answers:
Mean - 85.2
Median - 85
Mode - 85
Explanation:
Mean - 77+85+85+86+93=426/5 (the amount of data points given) = 85.2
Median - Organize the data points from least to greatest and eliminate the outermost numbers two at a time (one from both side) until you’re left with one.
Mode - The number that appears the most often in a given data set
divide the two:
52.50 / 7 = 7.50 per hour
Answer:
C=x (x+3)
Step-by-step explanation:
x cannot divide x+3 definitely so the denominators must be multiplied to get the least common denominator.
