Answer : option B
Given: center (4,2), vertex (9,2), and focus (4+2sqrt5,2)
The distance between vertex and center is 9-4 = 5
Center is (h,k) so h= 4 and k =2
focus is (h+c,k)
From the given focus (4+2sqrt5,2), c= 2sqrt(5)
Standard form of equation is
h= 4, k=2, a=5, c=2sqrt(5), we need to find out b
b^2 = 5
plug in all the values
Option B is correct

SOLUTION:
Let's establish the formula for a cylinder as displayed below:
Let volume of cylinder = V
V = ( Pi )r^2h
Now let's substitute the values from the problem into the formula to find the volume.
V = ?
r = 8
h = 4
V = ( Pi )( 8 )^2( 4 )
V = ( Pi )( 64 )( 4 )
V = ( Pi )( 256 )
V = 256( Pi )
FINAL ANSWER:
Therefore, the answer is:
C. 256( Pi ) units^3
Hope this helps! :)
Have a lovely day! <3
