Answer:
0.9 L of hardener
Step-by-step explanation:
Find the total mL then convert into L
60*15=900
900mL=0.9

Volume Formula [Cylinder]:
![\displaystyle V = \pi r^2 h](https://tex.z-dn.net/?f=%5Cdisplaystyle%20V%20%3D%20%5Cpi%20r%5E2%20h)
- <em>r</em> is radius
- <em>h</em> is height
Step-by-step explanation:
<u>Step 1: Define</u>
<em>Identify given variables</em>.
<em>h</em> = 5 cm
<em>r</em> = 10 cm
<u>Step 2: Find Volume</u>
- [Volume Formula - Cylinder] <em>Substitute</em> in variables:
![\displaystyle V = \pi (10 \ \text{cm})^2 (5 \ \text{cm})](https://tex.z-dn.net/?f=%5Cdisplaystyle%20V%20%3D%20%5Cpi%20%2810%20%5C%20%5Ctext%7Bcm%7D%29%5E2%20%285%20%5C%20%5Ctext%7Bcm%7D%29)
- [Order of Operations] Evaluate:
![\displaystyle V = 500 \pi \ \text{cm}^3](https://tex.z-dn.net/?f=%5Cdisplaystyle%20V%20%3D%20500%20%5Cpi%20%5C%20%5Ctext%7Bcm%7D%5E3)
- Approximate:
![\displaystyle V \approx \boxed{ 1570.8 \ \text{cm}^3 }](https://tex.z-dn.net/?f=%5Cdisplaystyle%20V%20%5Capprox%20%5Cboxed%7B%201570.8%20%5C%20%5Ctext%7Bcm%7D%5E3%20%7D)
∴ the volume of a cylinder whose height is 5 cm and radius is 10 cm is <em>approximately</em> 1570.8 cm³.

The ramp is simply a right triangle when viewed from the side. The rise is the height of the triangle and the run is the length or base. The slope of the ramp is the angle that the ramp makes with the ground. Plug those values into the formula for tanФ = opposite/adjacent or rise/run and solve for Ф. You should end up with 0.23
