Remember, the volume formula of a sphere is
![\frac{4}{3} \pi r^{3}](https://tex.z-dn.net/?f=%20%5Cfrac%7B4%7D%7B3%7D%20%20%5Cpi%20%20r%5E%7B3%7D%20)
.
Set that equation equal to whatever volume they give you and solve for r.
![\frac{4}{3} \pi r^{3}](https://tex.z-dn.net/?f=%20%5Cfrac%7B4%7D%7B3%7D%20%5Cpi%20r%5E%7B3%7D%20)
=
![\frac{9}{16} \pi](https://tex.z-dn.net/?f=%20%5Cfrac%7B9%7D%7B16%7D%20%5Cpi)
Now solve for r! I know you can do this. If you need help, just comment.
Step-by-step explanation:
The ratio of the two shorter legs of the top triangle is
![\dfrac{5}{4} = 1.25](https://tex.z-dn.net/?f=%5Cdfrac%7B5%7D%7B4%7D%20%3D%201.25)
The bottom triangle has the following ratio:
![\dfrac{7.5}{6} = 1.25](https://tex.z-dn.net/?f=%5Cdfrac%7B7.5%7D%7B6%7D%20%3D%201.25)
Since their ratios are the same, this means that the two triangles are similar.
Answer:
Price per bottle is 1.5 or $1.50
Step-by-step explanation:
To get price per unit, you just divide the amount of money spent by the items purchased. 9/6 = 1.5
