The radius of a cone-shaped tank is 4 feet less than its height. If the height of the tank is (x - 3) feet, the expression below shows the volume of the tank:

1 over 3π (x - 7)2 (x - 3)

What does the factor 1 over 3(x - 7) represent?

Oh and also, can someone answer this: 4(-2) - 3 - 2(-2) ,,, Is it -7?

@peachpi @xapproachesinfinity help?

xapproachesinfinity · Answer

the volume of a cone is 1/3 the volume of cylinder

xapproachesinfinity · Answer

what is the volume of a cylinder

anonymous · Answer

I dunno

xapproachesinfinity · Answer

volume = pi (radius squared) (height)

xapproachesinfinity · Answer

volume of a cone =1/3 pi (radius squared) (height)

xapproachesinfinity · Answer

we have the height as x-3

xapproachesinfinity · Answer

4 less than the height would be x-3-4=x-7
and that's 5he radius

so that means... im sorry I haven't done this in a super long time
