Answer:

A. h= \frac{355}{\pi r^2}

Step-by-step explanation:

Given:

Volume of cylinder = 355 cm^3

The volume of cylinder is given by :

V=\pi r^2h

where V represents volume,r represents radius and h represents height of cylinder.

The cylinder is being redesigned by a package designer who keeps the volume constant st 355 cm^3 and rearranges the formula to give height in terms of radius.

\pi r^2h=355      [ Substituting V=355 cm^3]

Dividing both sides by \pi r^2.

\frac{\pi r^2h}{\pi r^2}=\frac{355}{\pi r^2}\\\\h= \frac{355}{\pi r^2}

Answer:

y=3x-4

Step-by-step explanation:

The slope of the line is 3/1, 3 being the rise and 1 being the run. That's how you know that 3 is always going to be multiplied by x.

The -4 part is found by seeing where the line intersects with the y axis. Since the line crosses the y axis at -4, the equation will include -4.
