Answer:
21. [tex]\sqrt{\frac{-s}{15} }[/tex]
22. 87.92
Step-by-step explanation:
21. The quotient means division is going to happen between -s and 15. And then take the square root of that.
[tex]\sqrt{\frac{-s}{15} }[/tex]
22. The equation for the volume of a cylinder is this:
[tex]\pi r^{2} h[/tex]
The question gives you values for r, and h, so just substitute those values into the equation.
Here is the work:
[tex]\pi r^{2} h\\\\=\pi 2^{2} (7)\\\\=\pi(4)(7)\\\\=\pi (28)[/tex]
They told us to use 3.14 for pi, so i will substitute pi with 3.14
[tex]\pi (28)\\\\=3.14(28)\\\\=87.92[/tex]
