D = 2r
V = A*h
540π = πr²*h
540 = (d/2)²*15
540 = d²/4*15
540*4 = 15d²
d² = 2160 / 15
d² = 144
d = √144
d = 12 ft
(4,1) is the midpoint. Just find the middle of the two numbers and that will be your new point. Hope this helps!
Options:
(12,0) (0,12) (3,-1) (0,-4/3)

, (3,-1) and (0,-4/3)
Step-by-step explanation:
Given

Required
Which option is true?
A coordinate point is of the form; 
So, we have to substitute the x and y values in the given equation.
A. For (12,0)
and 
becomes



<em>This is true</em>
B. For (0,12)
and 
becomes



<em>This is false</em>
C. For (3,-1)
and 
becomes


<em></em>
<em></em>
<em>This is true</em>
D. For (0,-4/3)
and 
becomes





<em></em>
<em>This is true</em>
<em></em>
<em>Hence, (12,0)
, (3,-1) and (0,-4/3) are true values of the equation</em>
