Check the picture below, notice the base of the cone is really just a circle
thus
![\bf \textit{volume of a cone}\\\\ V=\cfrac{\pi r^2 h}{3}\qquad \begin{cases} r=radius\\ h=height\\ ----------\\ V=42\\ r=\sqrt{\frac{9}{\pi }} \end{cases}\\\\ -----------------------------\\\\ 42=\cfrac{\pi \left(\sqrt{ \frac{9}{\pi }} \right)^2h}{3}](https://tex.z-dn.net/?f=%5Cbf%20%5Ctextit%7Bvolume%20of%20a%20cone%7D%5C%5C%5C%5C%0AV%3D%5Ccfrac%7B%5Cpi%20r%5E2%20h%7D%7B3%7D%5Cqquad%20%0A%5Cbegin%7Bcases%7D%0Ar%3Dradius%5C%5C%0Ah%3Dheight%5C%5C%0A----------%5C%5C%0AV%3D42%5C%5C%0Ar%3D%5Csqrt%7B%5Cfrac%7B9%7D%7B%5Cpi%20%7D%7D%0A%5Cend%7Bcases%7D%5C%5C%5C%5C%0A-----------------------------%5C%5C%5C%5C%0A42%3D%5Ccfrac%7B%5Cpi%20%5Cleft%28%5Csqrt%7B%20%5Cfrac%7B9%7D%7B%5Cpi%20%7D%7D%20%5Cright%29%5E2h%7D%7B3%7D)
solve for "h"
The best answer I believe is C
Answer:
of ice cream
Step-by-step explanation:
Given
Number of friends = 8
Size of ice cream = 1/6 quarts
Required
Total ice cream served
Let n represent the number of friends, s represent the size of ice cream and t represents total ice cream served;
t is calculated as thus;
![t = n * s](https://tex.z-dn.net/?f=t%20%3D%20n%20%2A%20s)
![t = 8 * \frac{1}{6} quarts](https://tex.z-dn.net/?f=t%20%3D%208%20%2A%20%5Cfrac%7B1%7D%7B6%7D%20quarts)
![t = \frac{8}{6} quarts](https://tex.z-dn.net/?f=t%20%3D%20%5Cfrac%7B8%7D%7B6%7D%20quarts)
Divide numerator and denominator by 2
![t = \frac{4}{3} quarts](https://tex.z-dn.net/?f=t%20%3D%20%5Cfrac%7B4%7D%7B3%7D%20quarts)
Hence, she serves
in total
