If the length of OA is 1.80 units. Then the length of segment AB will be 0.80 units.
<h3>What is a Pythagoras theorem?</h3>The Pythagoras theorem states that the sum of two squares equals the squared of the longest side.
The Pythagoras theorem formula is given as
H² = P² + B²
Line AC is perpendicular to the circle centered at O with a radius of 1 unit. The length of AC is 1.5 units.
The figure is shown below.
Then the length of segment AB will be
AB = OA - OB
AB = OA - 1
Then the OA will be
OA² = OC² + AC²
OA² = 1² + 1.5²
OA² = 1 + 2.25
OA² = 3.25
OA = 1.80 units
Then we have
AB = 1.80 - 1
AB = 0.80 units

Answer:
Option B R(2,4) is correct
Step-by-step explanation:
The equation of the circle is:
Where r = radius
a and b are coordinates of the center of circle.
To check which point lies on a circle, we need to verify the equation
We will check for each option.
Option A Q(1,11)
x=1 and y =11
So, Option A is incorrect
Option B R(2,4)
x =2 and y = 4
Option B is correct.
Option C S(4,-4)
x =4 and y =-4
Option C is incorrect
Option D T(9,-2)
x =9 and y =-2
Option D is incorrect.
