The rule for a rotation by 90 about the origin is <span>(x,y)→(−y,x<span>)
so
</span></span><span>(-6,-2) ---> (2, -6)
(-3,1) </span> ---> (-1,-3)<span>
(-1,1) </span> ---> (-1,-1)<span>
(2,-4)</span> ---> (4, 2)

Step-by-step explanation:
Given
3 (t + 4 ) = 25.5
t + 4 = 25.5 / 3
t + 4 = 8.5
t = 8.5 - 4
t = 4.5
Hope it helps :)
The volume of the pyramid is a third of the volume of the prism which has the same base area and height as the pyramid. That is,
V = b²h / 3
Substituting the variables given,
V = (s²)(0.5s) / 3
Simplifying,
V = s³/6
