You are given a sheet of cardboard that is 8.0 in. x 11.0 in. how many full circles with a diameter of 3.0 inches can you cut from the cardboard? what is the percentage of waste if the excess cardboard (outside the circles) is thrown away?

The answer is there are eight circles that can be cut from an 8.0 x 11.0 in sheet but nine circles won’t fit.
Area of 8 circles is pir^2 = 8pi(1.5)^2 = 56.55 in^2

Total area of the cardboard = (8.0 in) (11.0 in) = 88.0 in^2
Area of waste = 88 in ^2 – 56.55 in^2 = 31.35 in^2
Percent of waste = 31.35 in^2 / 88.0 in^2 x 100% = 37.5% is the answer.

I'm pretty sure it's b). i try drawing the functions out and b is the one that stands out or isnt a "line"

Well in order to lose a pound you would have to burn 1,500 calories. the more calories you burn the more weight you lose. in order to lose 2 pounds you would have to run 4 hours and 28 minutes.
