−(7x^2+5x−18)

Factor.

1. 18 is negative, so a negative number multiplied by a postive number.

2. You can't factor 7, so 7x times x.

Find the radius of a sphere with a surface area of 1024π square inches

agasfer [191]

Answer:

Step-by-step explanation:

The formula of a Surface Area of a sphere:

$S.A.=4\pi R^2$

R - radius

We have

$S.A.=1024\pi\ in^2$

Substitute:

$4\pi R^2=1024\pi$ <em>divide both sides by π</em>

$4R^2=1024$ <em>divide both sides by 4</em>

$R^2=256\to R=\sqrt{256}\\\\R=16\ in$
