Answer:
It is 39.3
Step-by-step explanation:
You find the circumference using the formula 2πr so you get 20π.
and then you multiply that by 225/360 bc 360 is how much the whole circle is and the 225 part is the part you want to solve.
So 20π*225/360 is about 39.3
A quadrant is the area that is divided into the x and y axes
The quadrants in which tan
and cot
are positive are I and III
<h3>How to determine the quadrants</h3>
The tangent of an angle is calculated as:

While the cotangent of the angle is calculated as:

The above equations mean that:
For the tangent and cotangent of an angle to be positive, then the sine and the cosine of the angle must have the same sign.
- In the first quadrant, the sine and the cosine angles are positive.
- In the third quadrant, the sine and the cosine angles are negative.
Hence, the quadrants in which tan
and cot
are positive are I and III
