PART ;
......Circle A.................
Circumference - 2 pi r
25.12 = 2pi(4)
25.12 = 8i
Divide both sides by 8!!
3.14=pi
...Circle B.....................
Circumference = 2 pi r
9.42 = 2pi(3/2)
9.42 = 3pi
Divide both sides by 3!!!
3.14 = pi
PART B
.............Circle A...............
A=pi r ^2
50.24 = pi(4)^2
50.24=16pi
Divide both sides by 16!!!
3.14=pi
.............Circle B.............
A=pi r^2
7.065=pi(3/2)^2
7.065= 9pi/4
Divide both sides by 9/4!!!
3.14=pi
PART C
They used exactly 3.14 for the value of pi in CIRCLE A and B to get the circumference and the area :D
I hope this makes sense!!!
When I wrote 'pi', it was supposed to be the symbol for pi.
Answer:
1. What is the most common number of sit-ups completed in 1 minute? Explain how you used the dot plot to identify this number.
A: On the chart the number 38 has the most plotted dots.
2. What is the spread of this data set
A: 34 - 42
3. According to this data set, is Avery's guess of 30 sit-ups per minute too low, too high, or about right? Explain.
A: 30 is a little too low, the lowest count on the chart is 34, and Avery's estimate was 30, meaning its too low.

Answer:
You just need to find the area of each part and add them
Step-by-step explanation:
the answer is 48+20+THE BOTTOM 4TH
im not sure how to do the bottom because I can't seem to find the radius
