Step-by-step explanation:
The distance around a rectangle or a square is as you might remember called the perimeter. The distance around a circle on the other hand is called the circumference (c).
circle diameter radius
A line that is drawn straight through the midpoint of a circle and that has its end points on the circle border is called the diameter (d)
Half of the diameter, or the distance from the midpoint to the circle border, is called the radius of the circle (r).
The circumference of a circle is found using this formula:
C=π⋅dorC=2π⋅r

Answer:
4
Step-by-step explanation:
Since the first quartile is at 25%, 25% of 20 is 5. The median is the 50% mark of the set, and 50% of 20 is 10. So, there are 4 numbers between the 5th data point and the 10th, which are the 6th,7th,8th, and 9th data points.
