Let's solve your equation step-by-step.

−9−4b=3+8b

Step 1: Simplify both sides of the equation.

−9−4b=3+8b

−9+−4b=3+8b

−4b−9=8b+3

Step 2: Subtract 8b from both sides.

−4b−9−8b=8b+3−8b

−12b−9=3

Step 3: Add 9 to both sides.

−12b−9+9=3+9

−12b=12

Step 4: Divide both sides by -12.

−12b/−12=12/−12

b=−1

Anastasy [175]

Answer: \boxed{\ 28.26}

My step-by-step explanation:

  1. <u><em>We would use the formula πr2 (pi x radius x radius) </em></u>

<em>     </em><u><em>2.In this problem we were given the diameter of 6, in order to find the radius, you just divide by 2</em></u>

  • <u><em> And so we find:  6mm÷2=3mm </em></u>

   3. So now that we have our radius, we can just plug the numbers into the formula.  So this would be:

  • <u><em>πr2= 3.14 x 3 x 3= 28.26mm2</em></u>

<u><em /></u>

<u><em /></u>

Hope this helps you!
