Hi!





Explanation<em><u>: First you had to do is add m to from both sides. It gave us 13m+m=12-m+m. Then you can simplify, it gave us 14m=12. You can also divide by 14 from both sides. It gave us 14m/14=12/14. And the answer is going to be m=6/7 is the right answer. Hope this helps! And thank you for posting your question at here on Brainly. And have a great day! -Charlie</u></em>
Circumference = 2*pi*r
= 2 * 3.14 * 7
= 43.96 cm
Area = pi * r^2 (pi times radius squared)
= 3.14 * 7^2
= 3.14 * 49
= 153.86 cm^2 (153.86 square centimeters)
