Answer:
\boxed{\ 28.26}

My step-by-step explanation:

  1. We would use the formula πr2 (pi x radius x radius)

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

  • And so we find: 6mm÷2=3mm

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

  • πr2= 3.14 x 3 x 3= 28.26mm2

Hope this helps you!
