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
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
