Answer:
Step-by-step explanation:
volume=πr^2h
461.58=3.14*r^2*12
461.58=37.68*r^2
461.58/37.68=r^2
12.25=r^2
=r
3.5=r
diameter=radius*2
=3.5*2
=7 in.
volume of a cylinder= base area times height or pie (r) squared * (h)
461.58=pie r squared h
461.58=3.14*r squared *12
461.58=37.68*r squared
please do the rest .
2.19x=y
Hope this helps!
