Calculate the slope between (-5, -6) and (7, 9). Express your answer as a reduced fraction in the form n/d. If your answer is an integer, put it over 1. If the answer is negative, please put the negative sign first. If the answer is 0, type 0. If the answer is undefined, type UNDEF

1)  The formula for the volume of a right pyramid is 1/3* the area of the base * the height of the pyramid.  In this case, the base is a triangle, so our formula looks like this:
V=1/3(1/2bh)(H)
=1/3(1/2)(9)(15)(32)
=720 cm³.
2)  The formula for the volume of this square pyramid is V=1/3lwh.  Substituting our information we have:
V=1/3(18)(18)(12)
=1296 cm³
3)  The formula for the volume of any cone, oblique or right, is V=1/3πr²h.  Substituting our information, we have:
V=1/3π(6²)(10)
=1/3π(360)
=120π cm³
4)  Using our cone formula, V=1/3πr²h, we have:
V=1/3π(10²)(9)
=1/3π(900)
=300π cm³
