Answer:
A=80
B=31
C=64
Step-by-step explanation:
A, 69, and b will equal 180 since it forms a straight line
A+69+b=180
to solve for A we subtract 53+47 from 180 and get 80
80+69+b=180
to get B we subtract 80+69 from 180 and get 31
to get c we add 85+b and subtract it from 180 getting c=64

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.
