There are two circles, one represented by the equation (x+2)²+(y-6)²=729 and the other is represented by the equation (x-16)²+(y+49)²=28² a. which circle has a bigger area? explain how you know. be clear and complete. b. other than the area, how are these two circles different? be clear and complete.

a) The second one because it has a radius of 28 while the 1st one has a radius of square ( 729)=27

b) the two circles have different centers

1st cercle O ( -2, 6)

2nd one O' ( 16,-49)

and they don't have different radius as explained above

4 and 5)16.97 or 12√2

6)15.59 or 9√3

7)y = 15.59 or 9√3     x =27

8)17.80
