The snowfall from the Feb 10, 2018 snowstorm covered most of IA, northern IL, northern IN, and southern MI. While some locations in that snow swath saw over a foot of snow, let’s assume the average depth of the snow over this area was 9 inches. If the total area covered by the 9 inch average depth was 72,300 square miles, what percentage of the volume of the Grand Canyon would this amount of snow fill?

A. There are many tangent lines that contain point A.

Step-by-step explanation:

Given, Point A is on circle O.

A tangent line at a given point is the straight line that touches the curve at that point.A tangent line has to be perpendicular to the radius at this point. And perpendicular lines through a given point are unique.

That means, Statement A. "There are many tangent lines that contain point A" is wrong.

Diameter is the line drawn between two points of the circle that passes through the center, so statement B is correct.Chords are lines drawn between any two points of the circle, so statement  C is also correct.Radius is the distance from the center of the circle to its boundary, So statement D is also correct.
