find h now

OpenStudy (anonymous):

I got h = 2.53. However, that isn't one of my answer choices. Here are the choices I have: 4.56 cm 11.4 cm 22.8 cm 34.2 cm

OpenStudy (anonymous):

nope .check it again

OpenStudy (anonymous):

4034.66=(1/3)*pi*13*13*h

OpenStudy (anonymous):

Oh! I was dividing by 3 instead of multiplying by 3. I got 22.8 cm.
