Answer:
3 gallons at 3 dollars a piece
Step-by-step explanation:
2.25 •6=13.50
4.50•3=13.50
13.50+13.50= 27.00
36-27=9
9÷3=3
Answer:
volume = 450 mm³
Step-by-step explanation:
Given:
- height = 18 mm
- area of base = 25 mm²
Volume of a rectangular prism = area of base x height
⇒ volume = 25 x 18 = 450 mm³
The volume of the hemisphere is:_________________________________________________________"

or; write as: "
![\frac{2 \pi h^3}{3}](https://tex.z-dn.net/?f=%20%5Cfrac%7B2%20%5Cpi%20h%5E3%7D%7B3%7D%20)

Explanation:_________________________________________________________The formula/equation for the volume, "V", of a sphere:
V = (
![\frac{4}{3}](https://tex.z-dn.net/?f=%20%5Cfrac%7B4%7D%7B3%7D)
) *
![\pi](https://tex.z-dn.net/?f=%20%5Cpi%20)
* r³ ;
The depth; or, height, "h"; would represent the "radius", "r" .
So, the volume would be:
V =
![\frac{1}{2}](https://tex.z-dn.net/?f=%20%5Cfrac%7B1%7D%7B2%7D%20)
*
![\frac{4}{3}](https://tex.z-dn.net/?f=%20%5Cfrac%7B4%7D%7B3%7D%20)
*
![\pi](https://tex.z-dn.net/?f=%20%5Cpi%20)
* h³ ;
