Answer:
My step-by-step explanation:
- <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!
