As the radius of the circle is 5
You need to square this value for it to fit the equation
5^2 = 25
Thus, your answer would be option B

If your looking for the equation it would be 3.95 + 0.85t = Price
<span>Standard Form of an Equation of an Hyperbola opening up and down is:
(y-k)^2 / b^2 - (x-h)^2 / a^2 = 1
</span><span>where Pt(h,k) is a center with vertices 'b' units up and down from center.
</span><span>vertices: vertices: (0,+-2) b = 2 AND Center is (0,-0)
(y)^2/4-(x)^2/a^2=1
</span><span>foci: (0,+-7)
a^2 = 24
square root of 4 + a^2 = 5.29
4 + 5.29 = 9.29
y^2 / 4 - x^2 / 24 = 1</span>
2.04 divided by 4 is £0.51 per roll
4.68 divided by 9 is £0.52 per roll
4 pack is better deal because the 9 pack is more per roll
