For this case we must find an expression equivalent to:
According to the unit circle, 
is in the third quadrant and equals 210 degrees.
Then, we must find an expression equivalent to:
We have to:
It is in the fourth quadrant and is equivalent to 330 degrees, according to the unit circle.
Answer:
Option D
First, we need to find the area of the pond.
The formula for the area of a circle is: 3.14r^2
So, first of all, the radius is 10, and we need to square that, so 10 x 10 = 100.
There. Now, with the squared radius, we need to multiply that by pi.
100 x 3.14 = 314.
The area of the pond is 314 square meters.
Secondly, we need to find the number of frogs. If there are 2 frogs in each square meter, then 2 x 314 = 628.
There are 628 frogs in the pond.
