Okay to solve this you need to divide the volume to the two measurements
728 ÷ 8 = 91 ÷ 6.5 = 14
Answer:
<em>The equation of the Parabola</em>
<em>(y - 6 )² = 8 (x -6)</em>
Step-by-step explanation:
<u><em>Step(i):-</em></u>
Given directrix x = 4
we know that x = h - a = 4
h -a = 4 ...(i)
Given Focus = ( 8,6)
we know that the Focus of the Parabola
( h + a , k ) = ( 8,6)
comparing h + a = 8 ...(ii)
k = 6
solving (i) and (ii) and adding
h - a + h+ a = 8 +4
2 h = 12
h =6
Put h = 6 in equation (i)
⇒ h - a =4
⇒ 6 - 4 = a
⇒ a = 2
<u><em>Step(ii):-</em></u>
<em>The equation of the Parabola ( h,k) = (6 , 6)</em>
<em>( y - k )² = 4 a ( x - h )</em>
<em>(y - 6 )² = 4 (2) (x -6)</em>
<em>(y - 6 )² = 8 (x -6)</em>

Given:
Radius of the cylinder = 5 in
Height of the cylinder = 30 in.
To find:
The surface area of the cylinder.
Solution:
The surface area of the cylinder is:
Where, r is the radius and h is the height of the cylinder.
Putting 
in the above formula, we get
Therefore, the surface area of the cylinder is 1099 square inches.
Answer:
Step-by-step explanation:
The associative, commutative, and distributive properties of algebra are the properties most ... The Commutative Properties of Addition and Multiplication ... 14 + (−10) = 4 ... Note that y represents a real number. A) 5y • 2. B) 52y. C) 26 • 2 • y. D) y • 52 ... Here, the same problem is worked by grouping 5 and 6 first, 5 + 6 = 11.
