The fomula of a volume of a cylinder:

$V=\pi r^2H$

Cylinder A:

We have r = 1m and H = 4m. Substitute:

$V_A=\pi(1^2)(4)=\pi(1)(4)=4\pi\ m^3$

Cylinder B:

We have r = 3m and H = 12m. Substitute:

$V_B=\pi(3^2)(12)=\pi(9)(12)=108\pi\ m^3$

The ratio:

$\dfrac{V_A}{V_B}=\dfrac{4\pi}{108\pi}=\dfrac{4}{108}=\dfrac{4:4}{108:4}=\dfrac{1}{27}=1:27$

I think is that how many money will get each person

In this case is 320 for 4 people so it is 320 divided by 4

320/4= 80

so each person will get $80
