Answer:
<h2> 235 meters</h2>Step-by-step explanation:
This problem is on the mensuration of flat shapes, a circular shape.
the problem also requires that we find the perimeter of the circular track
the expression for the perimeter of a circle is given as
Given
diameter of the circular track = 75 meters
radius of circular track = d/2 = 75/2= 37.5 meters
Substituting our data into the expression for perimeter we have
<em>Approximately the length is 235 meters.</em>
Answer:
The answer to your question is: the first option - 9/
Step-by-step explanation:
Process
cosФ = adjacent side / hypotenuse
-1/9 = adjacent side / hypotenuse
adjacent side = -1 hypotenuse = 9
c² = a² + b²
b² = c² - a²
b² = 81 - 1
b = b = opposite side
But b is negative because we are in the third quadrant.
b = -
Finally csc Ф = hypotenuse / opposite side
csc Ф = - 9 /
