A roof rises 1.9 feet vertically and 5.9 feet horizontally. What si the grade of the roof?
To determine the grade of the roof, we need to calculate the ratio of the rise (vertical distance) to the run (horizontal distance). The formula for calculating the grade is:
Grade = (Rise / Run) * 100
In this case, the rise is given as 1.9 feet and the run is given as 5.9 feet.
Let's substitute these values into the formula:
Grade = (1.9 / 5.9) * 100
To solve this equation, divide 1.9 by 5.9:
Grade = 0.322 * 100
Multiply 0.322 by 100:
Grade ≈ 32.2
Therefore, the grade of the roof is approximately 32.2%.
