Question

A pyramid has a height of 461 ft and its base covers an area of 11.0 acres (see figure below). The volume of a pyramid is given by the expression

*V* =

3 |

*Bh*,

where *B*is the area of the base and *h* is the
height. Find the volume of this pyramid in cubic meters. (1 acre =
43,560 ft^{2})

Answer #1

A right square pyramid has a height of 50 meters (from the
center of the base to the apex) and a base with sides 50 meters
long. (a) Determine the volume of the pyramid. (b) Determine the
surface area of the pyramid, not including the base.
(a) Determine the volume of the pyramid.
(b) Determine the surface area of the pyramid, not including the
base.

Suppose water is leaking from a tank through a circular hole of
area
Ah
at its bottom. When water leaks through a hole, friction and
contraction of the stream near the hole reduce the volume of water
leaving the tank per second to
cAh
2gh
, where
c (0 < c < 1)
is an empirical constant.
A tank in the form of a right-circular cone standing on end,
vertex down, is leaking water through a circular hole in its...
