Answer:
1)37.68
2) 113.04
Explanation:
So for number 1, circumfence is diameter times pi, so diameter is 12 and assuming 3.14 for pi then 12(3.14)=37.68
Number 2, the area of a circle is pi(radius)^2 so we know the diameter is 12 and to find raidus we divide 2 since raidus is half of the diameter, square the radius which is 6^2 which will give you 36, assuming pi is 3.14 multiply 36 by 3.24, 36(3.14)=113.04
