Answer:35
Step-by-step explanation:
Answer:
diameter
circumference
diameter
Step-by-step explanation:
First, find the length of the diameter (d) and the length of the circumference of the circle (c).
Next, divide the length of the circumference c by the length of the diameter d and set up an equation
where the ratio equals to (the definition of )
Then, solve the equation for the circumference c:
Finally, substitute 2 times the radius for the diameter
You can use tangent trigonometric ratio since that deals with perpendicular and base and since the case is related physically to right triangle, thus it would be useful here.
The height of the considered pole is given by Option B:
<h2>Given that:</h2>
- The person is standing 36 feet away from base of a pole.
- The angle of elevation from base of person to top of pole is 30 degrees.
<h3>To find:</h3>
Height of pole.
<h2>Using tangent ratio to find height of pole:</h2>
Let the height of the pole be x.
In the given figure attached below, we can see that there is a right angled triangle ABC forming.
By using the tangent ratio from angle C, we have:
Thus, the height of the considered pole is given by Option B:
