The first board is approximately 0.45 the second board is approximately 0.9 and the third board is approximately 19.8
Answer:
radius ≈ 17.0 units
Step-by-step explanation:
The radius is the distance from the centre of the circle to a point on it.
Calculate the radius r using the distance formula
r = 
with (x₁, y₁ ) = (- 6, 1) and (x₂, y₂ ) = (7, 12)
r = 
= 
= 
=
≈ 17.0 ( to the nearest tenth )
I think it’s -12 3/8 (sorry if i’m wrong)
