Question:

A window is built in the shape of a semi-circle. If the window is 5 foot across at the bottom and has three stained glass sections of equal size, what is the area of each stained glass section? Round to the nearest foot.

Laken J.

Answer:

the area of each section would be rounded to 3 feet. area of a circle is pi x r^2. since it is a semi circle we would divide that by two. unrounded that would be around 9.8125. we would then divide that by 3 because there are three equal sections to get 3.270. It would be rounded down to 3 because 2 is less than 5.

Answer:

16, order of operations means that you would do what is in the parentheses first (6-3), then square that to get 9, then multiply 4 by 9 to give you 36, lastly take -20 and add 36 to get positive 16.
