If the area of a square is $575$ square units,then the approximate value of its side is

Find the approximate value of $(0.009)^{\frac{1}{3}}$.

Use differentials to approximate $(25)^{\frac{1}{3}}$.

If the percentage error in the radius of a circle is $3\%$,then the percentage error in its area is:

The approximate value of $\cos \left(59^{\circ} 30^{\prime}\right)$ is (given $1^{\circ} = 0.0175^{c}, \sin 60^{\circ} = 0.8660$)

The radius and the height of a right circular solid cone are measured as $7 \text{ ft}$ each. If there is an error of $0.002 \text{ ft}$ for every foot in measuring them,then the error in the total surface area of the cone (in $\text{sq. ft}$) is:
