Answer:
The area of a circle is given by the formula
area=πr2
we have the value of π=3.14 , and the radius is taken from the diameter of the window (bottom edge), using the relation:
r=diameter
2r=362
r=18
By substituting these values to the formula of a circle, we now have:
area= (3.14 ) (18) 2
area=1017.36
But since the window is a semicircle, the area will have to be divided in half, therefore,
area of a semicircle =1017.362
area of a semicircle = 508.68
Thus the window's area is equal to 508.68 sq in.
Answer: D. $0.90
Explanation:
Day 1 = $0.10
Day 2 = $0.10 + double the last fine which is $0.20 = $0.30
Day 3 = $0.30 + $0.30 = $0.60
Day 5 = $0.60 + $0.30 = $0.90
Its like abundance (quantity ) of which is called amplitude (quantity) of the particular square
