Answer:
12.5 pi or 39.26990
Step-by-step explanation:
First we can find the radius, which is half the diameter, 5 feet. To find the area of a semi-circle we would find the area of the circle and then divide by 2:

We can substitute what we have:

This gives us:
12.5 pi or 39.26990(Not sure what format you need it in)
I'm not sure for number one, but for number 2 the answer to that one is the second tallest on the chart or on the histogram. For number 3 I'm not sure because i cant see the numbers there too blurry. I'm sorry but i hope i got the second one correct.
Answer:
70.6
Step-by-step explanation:
The mean is the average of a set of numbers.
To find it, add up all the terms and divide it by the number of terms.
70 + 67 + 79 + 66 + 64 + 80 + 64 + 75 = 565
565 / 8 = 70.625
Rounding this to the nearest tenth, we get an answer of 70.6
