Question

Find the volume of a cylinder with a diameter of 8 inches and a height that is three times the radius. Use 3.14 for pi and round your answer to the nearest hundredth. (Hint: You may only enter numerals, decimal points, and negative signs in the answer blank. My answer is 603.19. Is my answer correct?

Answer 1

wait no is it 602.88?

Answer 2

Hi there!
Welcome To OpenStudy!! :)
We know the diameter is 8
to find the radius: diameter/2=8/2=4 <--this is the radius
For the height we have "a height that is three times the radius."
4*3=12
h=12
Now you plug that into the formula
\[\huge~\rm~\bf~v=(3.14)(4^2)(12) \]
From here do the math to get your final answer (which you said was 603.19) which is correct

Answer 3

would 602.88 be correct?

Answer 4

If I use pi it would be 603.19 but if I use 3.14 it would be 602.88.
