The area for a circle formula is πr².
Using the radius, we get:
π×7² =
49π ≈
153.938 ≈ (Using the π key)
153.9 ft²
To answer this question you will need to calculate the mean for each of the Shifts and then compare those means to the mean of all the data given. I have attached a picture of the means for each shift and the population mean (all the data).
Shift 1 is the closest to the population mean. It is 37.4, and the population mean is 35.9.

Answer: 21
Step-by-step explanation:
Given : Lindsay and Lorraine are trying to match the jump rope world record.
Number of jumps they need to jump together in a row = 48
Lindsay has gotten 14 jumps in a row, and Lorraine has gotten 13.
Total jumps = 14+13=27
Let 'j' be the number of more jumps they need to match the record.
j= Total jumps needed - Total jumps they already gotten
⇒ j= 48-27
⇒ j= 21
Hence, they need 21 more jumps to match the record.
The answer is: A
