Answer:

11

Step-by-step explanation:

Method A

(3*\pi )*11\approx103.62

(4*\pi )*11\approx138.16

138.16-103.62=34.54

34.54\div\pi\approx11

Method B

3\pi*11=33\pi

4\pi*11=44\pi

44\pi-33\pi=11\pi

A roof drops 6 feet for every 3 feet forword,determine the slope of the roof the slope can be positive or negative
dalvyx [7]

Answer:

The slope is -2

Step-by-step explanation:

Since the roof is decreasing in height as it goes forward, I know that the slope must be negative. The equation to find the slope is rise/run. The vertical change, or the rise, is -6 feet, so that value goes on top of the fraction. The horizontal value, or the run, is 3 feet so that goes on the bottom of the fraction.

Now our fraction is \frac{-6}{3}

If you simplify that fraction, you'll get -2.
