Answer:

(a variation of) vertex form

Step-by-step explanation:

For vertical scale factor "a" and vertex (h, k), the vertex form of the equation for a parabola can be written as ...

y = a(x -h)^2 +k

If k is subtracted from this equation, an alternate form is ...

y -k = a(x -h)^2

This latter version of vertex form is the form your equation has, where ...

a = 8
(h, k) = (-7, -20)

Rearrange the formula A = \pi r ^ ( 2) for r

tatyana61 [14]

Consider re-writing this formula as "A = pi*r^2." The backslash symbol "\" is unnecessary.

If A = pi*r^2, and we wish to solve for r, then divide both sides by pi:

A/pi = r^2

Taking the square root of both sides, sqrt(A/pi) = r (r must be positive in this situation).
