Y=cd-8
Add 8 to each side giving you
y+8=cd
Divide by d on each side giving you
C=(y+8)/d
To find the radius of the cylinder you will use the volume formula and solve for the radius.
V = pi x r^2 x h
83 = 3.14 x r^2 x 10
83 = 31.4 x r^2; divide both sides by 31.4
r^2 = 2.6; find the square root of 2.6
r = 1.6 in.
The radius is approximately 1.6 in.
