Acylinder has a height of 6 meters and a diameter that is 6 times the measure of the height. using 3.14 for pi, which of the following can be used to calculate the volume of the cylinder

So we know that the height = 6 m 
and the diameter is 6*6 = 36 m so from this result the radius = 36/2 = 18 m

so the volume of cylinder = area of base *height 

V = (18)^2 *pi *6 = 6104,16 m^3

hope helped 

Although the given statements are missing, the student's step-by-step solution is correct. The student had aimed to isolate the unknown variable in order to solve it. The student made sure the first step was to leave only one term in the side with the variable, before simplifying fractions.
