A cylinder with radius 7 centimeters and height 12 centimeters is shown. r = 7 cm
h = 12 cm
Enter the volume of the cylinder, in cubic centimeters. Round your answer
to the nearest hundredth.

step-by-step explanation:

step 1: solve one of the equations for one of the variables. let's solve the first equation for y:

step 2: substitute that equation into the other equation, and solve for x.

step 3: substitute x = 4 x = 4 x=4 into one of the original equations, and solve for y.
