Greetings and Happy Holidays!

The Formula for the Volume of a Sphere is: $V=\frac{4}{3}\pi r^3$

Input the value of the radius ( $\frac{d}{2}$ ):
$V=\frac{4}{3}\pi (2)^3$

Solve using the Order of Operations:
$V=\frac{4}{3}\pi (8)$

$V=\frac{4}{3}\pi \frac{8}{1}$

$V=\frac{32}{3}\pi$

The Answer Is:
$\boxed{V=33.510322}$

I hope this helped!

G(x) = 6x^2-7<br> Find g(x+2)

Ahat [919]

Answer:

= 6x² + 24x + 17

Step-by-step explanation:

g(x+2) = 6(x+2)² -7

= 6(x² + 4x + 4) - 7

= 6x² + 24x + 24 - 7

= 6x² + 24x + 17
