The approximate value of $(3.978)^{3/2}$ is

Find the approximate value of $(1.999)^{5}$.

There is a possible error of $0.03 \text{ cm}$ in a scale of length $1 \text{ foot}$ with which the height of a closed right circular cylinder and the diameter of a sphere are measured as $3.5 \text{ feet}$ each. If the radii of both cylinder and sphere are same, then the approximate error in the sum of the surface areas of both cylinder and sphere is (in square feet)

If $y=5x^2+6x+6$,$x=2$,and $\Delta x=0.001$,then the values of $\Delta y$ and $dy$ respectively are:

Find the approximate value of $(32.15)^{\frac{1}{5}}$.

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
