Find the shaded area of the figure shown, correct to one decimal place. Use the pi button on your calculator for pi in your calculations.
Answers
Answer:
204.2 square cm
Step-by-step explanation:
Area of the whole circle
PI x 9 squared =
PI x 81 = 254.4690...
Area whire circle
PI x 4 squared=
PI x 16 = 50.2654
Subtract white circle from the whole circle
254.4654 - 50.2654 = 204.2035...
The required area of the two concentric circles is given as 204.20 square cm.
Given that,
The shaded area of the figure shown, correct to one decimal place is to be determined.
The surface area of any shape is the area of the shape that is faced or the Surface area is the amount of area covering the exterior of a 3D shape.
Here,
According to the question,
Area of the shaded area = 3.14 [9]²- 3.14[4]²
Area of the shaded area = 204.20 square.
Thus, the required area of the two concentric circles is given as 204.20 square cm.

c = 10
then add all the measurements since it’s perimeter
10 + 6 + 8 = 24

You asked amusement park visitors the question “How many times did you ride the Ferris wheel today?” as they left the park.
Four people said they rode a Ferris wheel 5 times. Explain how this would be shown on a dot plot.
Answers
Answer:
Draw an xy axis. On the x-axis, put "number of times person rode the Ferris wheel" or something along those lines. For the y axis, put "frequency". For x = 5, you'll have four dots stacked on top of each other at this x value. I suggest having a slight gap between each dot so you can tell them apart. The four dots represent the four people who said they rode the Ferris wheel five times.

Part A: Explain why Jeff's line is NOT the best fit.
Part B: What would be a better line of best fit for the scatter plot?
Part C: How does the actual line of best fit compare with Jeff's line?
Answers
Answer:
The line of best fit would not be right because there would be a big gap of space. The line should be the cooardinate 7,3 as this covers the line and the cooardinate 7,7 is an outlier. The new line is more accurately placed
Step-by-step explanation:
Answer:
The actual line of best fit would be from (0, 0) to (7, 4), this is because it covers majority of the points. All the other points are just anomalies. Moreover, Jeff's line is NOT the line of best fit because it is not accurate and is out of place. Furthermore, the actualy line of best fit is 3 places lower on the y-axis then Jeff's line of best fit.
