Find the diameter of a circle with an area of 226.98

andrey2020 [161]

Remember the formula of the area of a circle is:
$V = \pi * r^{2}$
SO given that
V = 226.98
and $\pi = 3.14$
Plug in a chug
226.98 = 3.14 * $r^{2}$
$r^{2}= 72.287$
r = 8.50

Remember that d = 2 * r
d = 2 * 8.5 = 17

Quadratic equation. Find the value of m so that the roots of the equation (4 - m) x^2 + (2m + 4)x + (8m + 1) = 0 may be equal.

nikitadnepr [17]

The quadratic has one root with multiplicity 2 if the discriminant is 0, which is

$(2m+4)^2-4(4-m)(8m+1)$

(That is, for a quadratic $ax^2+bx+c$ , the discriminant is $b^2-4ac$ .)

Set the discriminant equal to 0 and solve for $m$ :

$(2m+4)^2-4(4-m)(8m+1)=0$

$4m^2+16m+16+32m^2-124m-16=0$

$36m^2-108=0$

$36m(m-3)=0$

$\implies m=0\text{ or }m=3$
