Answer:
1. 9 pi, 2. 121 pi
Step-by-step explanation:
The formula for circumference is pi d. So for the first question the radius would be three. The you do pi r ^2 for area so 3 times pi squared. Which is 9 pi. For the second you will do the same thing you will do 22 pi divided by 2 which is 11 pi then you will square 11pi and get 121 pi
129,407 because 12 ten thousands is 120,000 and 8 thousands is 8,000. 14 hundreds is 1,400 and 7 ones is 7 so 120,000+8,000+1,400+7=129,407
The points are (-3,3) and (2,2) then you use distance formula to find the distance between them
