Determine the area under the curvey y = √(a2-x2 included between the lines x = 0 and x = a.

Determine the area under the curvey y = √(a2-x2 included between the lines x = 0 and x = a.

We have y = √a,2, - x,2,⇒ y,2, = a,2, - x,2,⇒ x,2, + y,2, = a,2,Graph of above function is semi-circle lying above x-axis.,The graph is as shown in the following figure.
