Answer:

Step-by-step explanation:

We can first solve for the face diagonal. That is $\sqrt{(10^2+5^2)}$ . Notice this will form a right triangle with the vertical side. We get that the face diagonal = $\sqrt{125}$ . Now, we can use Pythagorean theorem again to get the straw length:

$s^2 = 9^2+\sqrt{125}^2$ where s = the straw length.

We can solve that s = $\sqrt{206}$

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
