Volume of square Pyramid = a^2 * h/3
If we rearrange that equation to give a (length of square base)
a = (sqrt(3)* sqrt(V))/sqrt(h)
a = (sqrt(3)* sqrt(100))/sqrt(12)
a = 5m
You can reverse the problem, and instead of dividing, you can use multiplication.
Answer: x= -2 and y=7
Step-by-step explanation:
4×20x+11y=37
20×4x+3y=13
Using elimination method
80x+44y=148
80x+60y=260
-16y/-16=-112/-16
Y=7
Substitute for Y in equation (1)
20x+ 11(7)=37
20x+77=37
20x=37-77
20x/20= -40/20
X= -2
therefore, x=-2 and y=7
Answer:
<em>D. Point Y is the center of the circle that passes through points </em><em>D, E, and F.</em>
Step-by-step explanation:
Circumcenter-
- The circumcenter is the center of the triangle's circumcircle and circumcircle is the circle that passes through all three of the triangle's vertices.
- Circumcenter is the point where the perpendicular bisectors of a triangle intersect.
As point Y is the circumcenter of triangle DEF, so the circle, which is the circumcircle, with centre as Y must passes through the vertices D, E, F.
