Step-by-step explanation:
1. You know that:
- The scale drawing shows a circular fountain with a diameter of 7 units.
- The diameter of the the actual fountain is 70 feet.
2. Then, to find the scale of the drawing, you can write the following fraction and simplify it:
[tex]\frac{7}{70}=\frac{1}{10}[/tex]
3. You can write it as a ratio:
1:10
This means that 1 unit=10 feet
