The first thing you do is find the area of the rectangle, which is l*w or 9*4 = 36. Then you find the area of the circle, which is pi*r^2 or pi*2^2 or 4*pi (do not combine pi and 4 yet). Lastly, you would subract the area of the circle from the area of the rectangle. It would be 36-4*pi, which equals about 23.43 ft.
Answer:
30 cents
Step-by-step explanation:
Before the sale 9 candy bars would be .2 x 9 = $1.80. 9 candy bars on the sale would be 9 divided by 3 times .5 which is $1.50. So the savings is 1.80 - 1.50 = .30 or 30 cents.

So, the nth term is:
Yes acute angles are less then 90 degrees and obtuse are more. Right angles are 90 degrees
Answer:
m∡1 = 95°
m∡2 = 85°
m∡3 = 95°
Step-by-step explanation:
m∡1 + 85 = 180; m∡1 = 95°
m∡2 = 85° because it is vertical and congruent to the angle measured 85°
m∡3 = m∡1 = 95° because they are vertical and congruent
