<h3>Answer:</h3>
6.8 inches
<h3>Explanation:</h3>
The shortest distance from P to the circle is along the line between P and the center of the circle. That line is the hypotenuse of the right triangle whose legs are PQ and QC (where C is the circle center).
The Pythagorean theorem tells you
... PC² = PQ² +QC²
... PC² = 13² +9² = 250
... PC = √250 = 5√10 ≈ 15.8114 . . . . inches
The distance from P to the circle is 9 in less than this, so is
... 15.8114 - 9 = 6.8114 ≈ 6.8 . . . . inches
The percent grade of the road will be 4.7692%.
<h3>How to calculate the percentage?</h3>
It should be noted that the difference will be:
= (1132 - 1070)/1.3 ÷ 1000
= 62/(1.3 × 1000)
= 62/1300
= 31/650
= 0.047692
Therefore, the percent grade of the road will be 4.7692%.
