a roof rises 2.4 feet vertically and 7.3 feet horizontally. what is the grade of the roof?
To find the grade of the roof, we need to calculate the ratio of the vertical rise to the horizontal run. The grade is often expressed as a percentage or a decimal.
Step 1: Identify the given vertical rise and horizontal run.
- Vertical rise = 2.4 feet
- Horizontal run = 7.3 feet
Step 2: Calculate the grade using the formula:
- Grade = (Vertical rise / Horizontal run) * 100
Substituting the given values:
- Grade = (2.4 / 7.3) * 100
Step 3: Simplify and calculate the value:
- Grade = 0.3288 * 100
- Grade = 32.88
Therefore, the grade of the roof is approximately 32.88%.
