You must recognize that this function is the top half of a circle. here's why: 9 - x^2 = y^2 x^2 + y^2 = 9

The graph of the semi-circle has its center point on the origin and a radius of 3:

You can then use the formula of the area of a circle to find the area of the region. Since the function is a semi-circle it is half of the circle. Therefore you must use the equation:

yes, very good!!
