I really need help with this

Step-by-step explanation:

what you have to do first is multiply 14x14 which give you 196 then multiply 29x29 which is 841,then what you do is add up 196+841= 1,087 then you square root 1,087 and the answer is 32.96 but then round it to the nearthest tenths which 9 so you final answer will be 33.0 which supossed to be 33/100 but I don't see that as answer

step-by-step explanation:

x^2 -12x + 36 + y^2 = 36

x^2 + y^2 = 12x

r^2 = 12rcos(theta)

r = 12 cos(theta)
