About how accurately must the interior diameter of a 10-m high cylindrical storage tank be measured to calculate the tank's volume to within 1% of its true value?

Show that the limit does not exist by approaching the origin along one or more of the coordinate axes.

$$\lim _ { ( x , y , z ) \rightarrow ( 0,0,0 ) } \frac { x + y + z } { x ^ { 2 } + y ^ { 2 } + z ^ { 2 } }$$

The width of a rectangular storage container is 1.25 times its height. The length of the container is 16 inches and the volume of the container is 2000 cubic inches. Find the dimensions of the container.

Evaluate the limit (limit as x approaches 0) of [sqrt(x+4)-2]/x

Segment $\overleftrightarrow{A C}$ & $\overleftrightarrow{B D}$ intersect at point O, then $\mathrm{m} \angle D O C = \mathrm{m} \angle 1$, $\quad \mathrm{m} \angle A O D = \mathrm{m} \angle 2$,$\mathrm{m} \angle A O B = \mathrm{m} \angle 3$ $\quad \mathrm{m} \angle B O C = \mathrm{m} \angle 4$. Apply the theorems of this section. If $\mathrm{m} \angle 1=x+20$ and $\mathrm{m} \angle 4=\frac{x}{3}$, find $x$ and $\mathrm{m} \angle 4$.
