Acircle fits inside a semicircle of diameter 24mm

calculate the shaded area
give your answer to 3 significant figures and state its units

The shaded are is

Step-by-step explanation:

we know that

The shaded area is equal to the area of the semicircle minus the area of the circle inside the semicircle

step 1

Find the area of semicircle

The area of semicircle is equal to

where

----> the radius is half the diameter

substitute

step 2

Find the area of the circle inside the semicircle

The area of circle is equal to

where

---> the radius of circle inside is half the radius of semicircle

substitute

step 3

Find the shaded area

assume

3 significant figures is

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.
