A=r^ 2 * pi=35^ 2 *3.14=3846.5m
Step-by-step explanation:
Plan B:
2:5 = 0.4 red to 1 white
1:4 = 0.25 red to 1 white
Students might also scale up using part-to-whole-ratios and come up with 35 parts total and 14 parts red for Plan A and 35 parts total and 7 parts red for Plan B.
<u><em>Hey There!</em></u>
<u><em>Perimeter=L+W×2</em></u>
<u><em>Perimeter=150+50×2</em></u>
<u><em>Perimeter=200×2</em></u>
<u><em>Perimeter=400</em></u>
Volume of twin sized mattress =
39* 8.75* 75 = 25593.35 cubic inch
Volume of queen sized mattress =
60* 8.75* 80 = 42000 cubic inch
To fill 25593.35 cubic inch it takes 4 minutes
To fill 1 cubic inch it will take =
minutes
So to fill 42000 cubic inch it will take =
= 6.56 minutes.
