Answer:
Center is (7,-6)
Our radius is 4
Step-by-step explanation:
Subtract 69 to both sides
Complete the square of the x terms and y terms.


(To complete the square divide the coefficient by 2 and square it).


Add those terms to the full equation. Add 36 and 49 to the right side as well

Simplify the x and y terms into a binomial.

Set the left side equal to zero separately to find the center and take the square root of the right side to find the radius.






So our center is (-7,6)
Our radius is 4.
we know that
1 ft-------> is equal to 12 in
step 1
find the area of the walk
18 in wide--------> convert to ft
18/12=1.5 ft
area=1.5*32------> 48 ft²
step 2
find the cost at $2.10 a square foot
multiply 48 ft² by $2.10
48*2.1=$100.80
therefore
the answer is
$100.80
