Pierce is making a rectangular frame for a photo collage that has a perimeter of 72.2 72.2 inches. The length of the frame is 20

Allushta [10]

Answer:

$P = 2x+2y$ (1)

And we know that the lenght is y = 20.3. If we solve for x from equation (1) we got:

$P-2y = 2x$

$\frac{P-2y}{2} =x$

And replacing we got:

$x = \frac{72.2 in -2*20.3 in}{2}= 15.8 in$

And the width for this case would be 15.8 in

Step-by-step explanation:

For this case we know that the photo is rectangular. Let's define:

x = the width, y= the length

And we know that the perimeter is given by:

$P = 2x+2y$ (1)

And we know that the lenght is y = 20.3. If we solve for x from equation (1) we got:

$P-2y = 2x$

$\frac{P-2y}{2} =x$

And replacing we got:

$x = \frac{72.2 in -2*20.3 in}{2}= 15.8 in$

And the width for this case would be 15.8 in

The volume inside of a sphere is V=4πr33 where r is the radius of the sphere. Your group has been asked to rearrange the formula

Semmy [17]

Answer:

Therefore,

$r=\sqrt[3]{\frac{3V}{4\pi }}$

is the required r

Step-by-step explanation:

Given:

Volume of inside of the sphere is given as

$V=\frac{4}{3} \pi r^{3}$

where r is the radius of the sphere

To Find:

r =?

Solution:

We have

$V=\frac{4}{3} \pi r^{3}$ ......Given

$3\times V=4\pi r^{3} \\\\\therefore r^{3}=\frac{3V}{4\pi } \\\\\therefore r=\sqrt[3]{\frac{3V}{4\pi }} \textrm{which is the expression for r}$

Therefore,

$r=\sqrt[3]{\frac{3V}{4\pi }}$

is the required r
