If $y=2x^3-2x^2+3x-5$, then for $x=2$ and $\Delta x=0.1$, the value of $\Delta y$ is:

Consider the following statements:
$A$ is the relative error in the area of a square when the relative error in its side is $0.4$.
$B$ is the relative error in the volume of a sphere when the relative error in its radius is $0.3$.
$C$ is the relative error in the surface area of a closed cylinder whose height is equal to its radius, when the relative error in its height is $0.2$.
$D$ is the approximate error in $y = x^2 + x - 3$ when $x = 2$ and $\delta x = 0.1$.
The ascending order of the values of errors in these statements is:

If $1^{\circ} = 0.0175 \text{ radians}$,then the approximate value of $\sec 58^{\circ}$ is

The value of $\sqrt{24.99}$ is

If the radius of a spherical balloon increases by $0.1 \%$, then its volume increases approximately by (in $\%$)

If the relative errors in the base radius and the height of a cone are same and equal to $0.02$, then the percentage error in the volume of that cone is
