Answer:
r = -6
Step-by-step explanation:
6(r - 8) = 8r - 36
distribute 6 into r - 8
6r - 48 = 8r - 36
add 36 to both sides
6r - 12 = 8r
subtract 6r from both sides
-12 = 2r
divide by 2 on both sides
-6 = r

Step-by-step explanation:
radius=4 as it is tangent to x-axis.
y co-ordinate of center is 4 so radius=4
eq. of circle is (x-2)²+(y-4)²=4²
or x²-4x+4+y²-8y+16=16
or x²+y²-4x-8y+4=0
