7} is
Text Solution
Verified by ExpertsC
The given curves are x 2
y, y
8 - x 2 and y
7
The point of intersection of the curves x 2
y and y
8 - x 2 is obtained by,
x 2 = 8 - x 2
x = ±2 and y = 4.
Hence the points are (2,4),(-2,4).
The points of intersection of the curves y
8 - x 2 and y
7 is obtained by,
8 - x 2 = 7
x = ±1 and y = 7
Hence the points are (1,7),(-1,7).
The required graph is

The required area is symmetrical about y-axis.
Hence required area is 


=
(8-0-l + 8)
= 20 sq units.
Hence, the required area is 20 sq units
