\(\pi\)
The correct option is(A): \(\pi\).
The area bounded by the circle and the lines, x=0 and x=2, in the first quadrant is
represented as

∴Area OAB=\(∫_0^20y dx\)
=\(∫_0^2√4-x^2dx\)
=\([\frac{x}{2}\sqrt{4-x^2}+\frac{4}{2}sin^{-1}\frac{x}{2}]_0^2\)
=\(2(\frac{π}{2})\)
=π units
Thus, the correct answer is A.
Determine whether each of the following relations are reflexive, symmetric, and transitive.
Show that the relation R in the set R of real numbers, defined as
R = {(a, b): a ≤ b2 } is neither reflexive nor symmetric nor transitive.
Check whether the relation R defined in the set {1, 2, 3, 4, 5, 6} as
R = {(a, b): b = a + 1} is reflexive, symmetric or transitive.
Using integration finds the area of the region bounded by the triangle whose vertices are (–1, 0),(1, 3)and(3, 2).
Using integration find the area of the triangular region whose sides have the equations y =2x+1,y=3x+1 and x=4.
