Answer:

11.28 units squared

Step-by-step explanation:

Area of a circle is

$\pi {r}^{2}$

each square has an area of 1

There are four semi-circles, which make two complete circles.

the area of the 5 squares plus the area of the two circles equals the total area.

5 + 2(3.14) = 11.28

The mean of a data sample can be found by adding all the terms in the data sample and dividing the result by the number of terms. In the first case we have the following data sample:

$12,8,15,11,9$

The mean of this sample is:

$\operatorname{mean}=\frac{12+8+15+11+9}{5}=\frac{55}{5}=11$

The mean absolute deviation is the sum of the differences between each data value and the mean, divided by the number of data values, the formula is:

$MAD=\frac{\sum ^{}_{}\mleft|x_i-\bar{x}\mright|}{n}$

Therefore, we must calculate the positive difference between each value and the mean, add them up, and divide the result by the number of data points in the sample. In the case of the first sample we get:
