उत्तर

Let A be the required area.

Given equation of the curve is x = `sqrt(25 - y^2)`

∴ A = `int_0^5 x  "d"y`

= `int_0^5 sqrt(25 - y^2)  "d"y`

= `int_0^5 sqrt((5)^2 - y^2)  "d"y`

= `[y/2 sqrt((5)^2 - y^2) + (5)^2/2  sin^-1 (y/5)]_0^5`

= `[5/2 sqrt((5)^2 - (5)^2) + (5)^2/2 sin^-1 (5/5)] - [0/2 sqrt((5)^2 - 0) + (5)^2/2 sin^-1 (0/5)]`

= `0 + 25/2 sin^-1 (1) - 0`

= `25/2 (pi/2)`

= `(25pi)/4` sq.units
