Answer:
400 tiles :)
Step-by-step explanation:
2/5 = 160/x
1/5 = 80/x
80 *5 = 400
The midpoint of the points ( 4, 5.5 ) and ( 4, 10.5 ) is the center of the circle:
C =

C = ( 4, 8 ), h=4, k=8
r =

r = 2.5
The equation of the circle in standard form:
( x - h )² + ( y - k )² = r²
( x - 4 )² + ( y - 8 ) = 6.25
-9 is the slope of the line.
