Answer 3

V=πr^2h=π*12.2^2*9
≈4208.35186mm^3

Answer 4

what is the letter of the ans

Answer 5

V=πr^2h=12.2^2*9*π
=1339.56π mm^3

Answer 6

what is the letter

Answer 7

Recall that the volume of a cylinder is given by pi*r^2*h; that is, pi times the radius squared times the height.

The radius squared times the height is 1339.56. Pi is an irrational number, so any time you try to multiply something by it in your calculator, the calculator has to give up and just make a close guess. Calculators are very good, but they still only give an approxmiation.

The only way to give the exact answer is by saying 1339.56PI, which is B
