<span>D = 22ft
h = 9 ft
Lateral area of the cylinder = </span>π × D × h = 3,14 × 22 × 9 = 621,72 ft²
Answer:
the answer is 4.857142857.
6d+8=14+3d
6d=14-8+3d
6d-3d=14-8
3d=6
D=6/3
D=2
Answer:
c
Step-by-step explanation:
Given:
A parabola opens up or down and its vertex is at the point (h, v).
To find:
The equation of the parabola.
Solution:
A parabola opens up or down. It means it is a vertical parabola.
The vertex form of a vertical parabola is
...(i)
Where, a is constant and (h,k) is vertex.
The vertex of given parabola is at point (h,v). Putting h=h and k=v in (i), we get

The required equation of the parabola is
.
Therefore, the correct option is A.
