The area (in sq. units) of the region bounded by $y = -1, y = 2, x = y^3$ and $x = 0$ is equal to

The area of the region bounded by y² = 9x, x = 2, x = 4 and the x-axis in the first quadrant, is

Area of region bounded by the curves $x = y^3$, $x = 0$ between $y = -1$ and $y = 2$ is:

The region bounded by curve $y = x|x|$, x-axis and lines $x = \pm 1$ is best represented graphically by :

The area bounded by the y-axis, $y=\cos x$ and $y=\sin x$, when $0\leq x\leq\frac{\pi}{4}$, is

The area (in sq. units) of the region bounded by the parabola $y^2 = 4x$ and the line $x = 1$ is

If the area bounded by curves $y = 2^{kx}$, $x = 0$, $x = 2$ in first quadrant is $\frac{3}{\log 2}$, then $k$ is ($k \neq 0$)
