Mary is a scientist. Using a microscope, she looks at a salt crystal and discovers it is shaped like a cube. Each square face has side length 0.1\text{ mm}0.1 mm0, point, 1, space, m, m.

the formula for the equation of a circle is (x – h)2+ (y – k)2 = r2, where (h, k) represents the coordinates of the center of the circle, and r represents the radius of the circle. if a circle is tangent to the x-axis at (3,0), this means it touches the x-axis at that point.
