The formula for this is

. If the diameter is 8 the radius is 4, so filling in accordingly we have

and

which is

and when you multiply in 3.14 you get that A = 401.92 or B above.

Answer:
a = 3
Step-by-step explanation:
-12x³+14x²+6x = -2x(ax+1)(2x-3)
<em>Divide both sides by -2x(2x-3)</em>

ax+1=3x+1
<em>Subtract 1 from both sides</em>
ax=3x
<em>Divide both sides by x</em>
a=3
