Answer:
760.270in^3
Step-by-step explanation:
1) volume of a cylinder formula:
Pi*r^2*h
So lets find the volume of outer cylinder first
Pi*6^2*22
Pi*36*22=2488.14138164
Now we need to find volume of inner ring:
Pi*25*22=1727.87595947
Subtract inner from outer collar to get the volume of the inner collar only
2488.14138164-1727.87595947=760.265
Rounded: 760.27
