Use the formula for the volume of a cylinder which is V=(pi)r^2 h and substitute to get V=(pi)1.2^2 (4). then solve to get about 18.1. then multiply that by the cost, 22 to get about $398.10.
Solpe intercpt form is y=mx+b m=slope b=y intercept so exg if you have 3x+8y=8 subtract 3x from both sides 8y=3x+8 divide boh tsides by 8 y=8/3x+1 y intercpt=1 slope=8/3
