Answer:
79
Step-by-step explanation:
The area of a circle is pi*radius^2; the radius of this circle is 10 (20/2=10). Our area is then 100pi or ~314 square feet. A 2x2 square takes up 4 feet. 314/4 is equal to 78.5, or when rounded, 79
Answer: The Last option is the only option equivalent to that equation.
Yes I think it’s s right triangle
The given equation is

First we solve for y, and for that, we have to islolate y, that is

And it pass the vertical line test. So here y is a function of x .
So we can define the given equation as y as a function of x .
Well, 100 - 16 = 84, and 84 divided by 12 is 7. She needs to buy 7 more boxes of granola bars for her students.
