46 - 50 miles per hour, 18 number of vechiles. what % of the vehicles were traveling between 46 and 50 miles per hour?

pi x^2

step-by-step explanation:

pi times x squared

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.
