In a unit circle what quadrant is 7 in?

First divide the diameter by 2, to get the radius. Then use the formula area = pi x radius2.

Quadrants 2 and 3.

A unit circle is a circle with radius equal to one.

Pi radians is half a circumference, (7/12) pi is a little more than a quarter circle. To convert to degrees, multiply the radians with 180/pi; in this case, the result is 105 degrees.

The unit circle is a circle that can be used to find trigonometric functions. The equation of the unit circle is x^2 + y^2 = 1. So it is any circle with radius 1.
