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
So, Lets Find The Volumes. Lets Find The Rectangular Pan's First. We Have To Do 6*9*2 For The Volume. 6*9 = 54. Now, Lets Multiply By Two. 54*2 = 108. So, The Rectangular Pan Is 108 in.^3. Now, Lets Do The Cylinder. We Do 3.14*(7/2*7/2) * 2. 7/2 = 3.5. 3.5*3.5 = 12.25. Now, Do 12.25*3.14. This Gives You 38.465. Now, Multiply By 2. This Gives You 76.93. Now, We Have Found A To Be The Bigger Cake Volume Would Be Made In The Rectangular Pan.
