Best answer gets brainliest! The following three shapes are based only on squares, semicircles, and quarter circles. Find the perimeter and the area of each shaded part. Give your answer as a completely simplified exact value in terms of π (no approximations).

A = 81 - 20.25π

P = 36 - 9π

Step-by-step explanation:

To find the perimeter and area of the highlighted shapes, we must find those of the square and full circle. Then subtract the circle's area from the square. Do the same for perimeter.

an advantage of the standard deviation is that it increases as the dispersion of the data increases. e. the interquartile range is preferred when the data are not skewed or no have outliers. an advantage of the standard deviation is that it uses all the observations in its computation.
