Answer:
i didn't understand what your question is
Remember the formula of the area of a circle is:

SO given that
V = 226.98
and

Plug in a chug
226.98 = 3.14 *


r = 8.50
Remember that d = 2 * r
d = 2 * 8.5 = 17
The quadratic has one root with multiplicity 2 if the discriminant is 0, which is

(That is, for a quadratic
, the discriminant is
.)
Set the discriminant equal to 0 and solve for
:
