Answer:
<h2><em>
vol= 10366.3175in²</em></h2>
<em></em>
Step-by-step explanation:
So this is a cylinder
<h2>formula:
π r²h</h2>
R= 8.75in
h=43.12in
So it will be = 3.14x8.75²x43.12
=> 3.14x76.5625x43.12
3.14x 3301.375

Answer:
846 m³
Step-by-step explanation:
The solid consists of a rectangular prism and a rectangular pyramid.
V = LWH + (1/3)LWh
V = 9 m * 6 m * 12 m + 1/3 * 9 m * 6 m * 11 m
V = 648 m³ + 198 m³
V = 846 m³
Where p is the distance the focus is above the vertex, the equation of a parabola with vertex (h, k) can be written as
... y = 1/(4p)·(x -h)² +k
The vertex is halfway between the focus and directrix. The focus of your parabola is on the y-axis at y=6, and the directrix of your parabola is at y=-6, so the vertex of your parabola is on the y-axis at y=0. That is, the vertex is
... (h, k) = (0, 0).
The distance p from the focus at y=6 to the vertex at y=0 is 6 units, so
... p = 6.
Filling these values into the equation gives
... y = 1/(4·6)·(x -0)² +0
... y = (1/24)x²
