Caroline knows the height and the required volume of a cone-shaped vase she’s designing. Which formula can she use to determine

timama [110]

Answer:

Option B. $r=\sqrt{\frac{3V}{\pi h}}$

Step-by-step explanation:

we know that

The volume of a cone is equal to

$V=\frac{1}{3}\pi r^{2} h$

Solve for the radius r

That means-----> isolate the variable r

Multiply by 3 both sides

$3V=\pi r^{2} h$

Divide by $(\pi h)$ both sides

$r^{2}=\frac{3V}{\pi h}$

square root both sides

$r=\sqrt{\frac{3V}{\pi h}}$

Which of the following are in correct order from greatest to least?

Marat540 [252]

Given:

Four series of angles are given.

To Find:

Identify the series with the correct order from greatest to least.

Solution:

the correct order from greatest to least is what is shown in the fourth option, i.e.,

$330$

Calculation:

Now, we use the fact that

$\pi =180$

to calculate the values of

$\frac{\pi}{2}, \frac{2\pi}{3}, \frac{7\pi}{6}, \frac{5\pi}{3}$

So, we have

$\frac{\pi}{2} = 90\\\\\frac{2\pi} {3}=\frac{(2)(180)}{3} = 120\\\\ \frac{7\pi} {6}=\frac{(7)(180)}{6} = 210\\\\ \frac{5\pi} {3}=\frac{(5)(180)}{3} = 300\\\\$

Looking at the above values, we see that the correct order from greatest to least is what is shown in the fourth option, i.e.,

$330$
