Let us work this out the first thing we do in order to work on volumes, we need write
down the formula but first. What is a volume again? Volume is the amount of space occupied
by a solid, so we are looking in here how many meter are cube are they? Because Of course
the unit are in meters, meters cube is three dimensional we are looking out at the volume
of space inside this particular shape equal, let us write down that formula so a volume
of a cylinder is pi r squared x height or length, so lets us look at this cylinder. I said before the
radius is 3m and the length of height is a grand total of 9m, so all we need to do is
drag and drop those numbers and substitute to the formula and now we will come up with
the final volume. So volume v =pi x radius I said was 3 and
that is going to be 3 squared x the height or the length which is 9m. simplify volume
equals pi x 9 x 9, 9 x 9 is 81. Volume the complete volume inside that space are this
cylinder in total is 81 x pi or 81 x 22 over 7 or 81 x 3.14 etc. put that in your calculator
the grand total in meter cube is v=254.47 m squared, that is in two decimal places.
