Area of a Circle: The area of a circle is the amount of space the circle takes up. To compute the area of a circle, we use the formula a=πr^2 where r is the radius of the circle.
Radius: The radius of a circle is the distance from the center of the circle to any point on the circle.

Answer: The angle is in the second quandrant
Step-by-step explanation: 
If sin of theta is greater than 0, the angle theta has to be in either the first or second quandrant. If tangent of theta is less than 0, it cannot be in the first or third quandrant. Therefore, we know the angle is in the second quandrant.
