A rectangle is placed around a semicircle as shown below. The length of the rectangle is . Find the area of the shaded region. Use the value for , and do not round your answer. Be sure to include the correct unit in your answer.

15.48mm

Step-by-step explanation:

I'm guessing some stuff because I don't know what the semicircle actually looks like so uh...

Shaded area = rectangle area-semicircle area

rectangle area = 12 * 6 (the height is 6 because it is the radius of the semicircle) = 72

semicircle area= (6^2pi)/2=18pi=56.52

72-56.52

=15.48

i would need to see the dot plot : )

the total estimated nappy use.=10,500,000

step-by-step explanation:

given that on an average the average baby uses 3528 napkins.

in a particular year 2014, the number of births were 299697 in new south wales.

rounding off the number of births to the nearest hundred thousand we have

no of birtsh = 300000

also rounding off the average usage to nearst thousand we get

average use of a baby = 3500

hence total number of nappy estimated to be used = 3500x300000

= 10,500,000

answer is 10,500,000 nappies
