# Find the area of

Answer :

The equations of the given lines are

y = x (i)

and x2 + y2 = 32 (ii)

from (i) and (ii), we get that the line and circle intersect each other at B(4,4) in the first quadrant. Draw perpendicular BM to x-axis.

Therefore, the required area = area of the region OBMO + area of the region BMAB.

Now, the area of the region OBMO = = The area of the region BMAB = = = = = =8π –(8+4π) =4π -8

Thus, the required area = area of the region OBMO + area of the region BMAB.

= 8 + 4π -8 = 4π sq units.
