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

i think it is everything has to equal 180 so, if i correct 4=c. 6=d. 8=a. 7=b. and the last question would be c. because they are parallel lines and they are congruent.

step-by-step explanation:

the reason everything has to equal to 180 is because that is how it works. i'm guessing that is its rule. 4 and 8 are congruent and parallel so, that would be 30+30 because they have the same number. it would equal 60. 6 and 7 are congruent and parallel so, that would be 30+30 because they have the same number. it would equal 60. 60+60 is 180. so, now you have your answer
