Answer: 904.32 cubic units.

Step-by-step explanation:

The formula for a sphere's volume is V = $V = \frac{4}{3}\pi r^{3} \\$

Substitute pi for 3.14 and radius for 6. 6^3 = 216

$\\V = \frac{4}{3}\ (3.14)( 216) \\\\$

Multiply them together, the answer is 904.32 cubic units.

8 x 2 + 6x + 5=0
16 + 6x + 5=0
6x+21=0
6x+21-21=0-21
6x=-21
6x/6=-21/6
x=-7/2
