Diameter of the basketball rim = 18 inches
Circumference of the standard basketball = 30 inches
Area of circle = π r²
Basketball rim = 3.14 * (18/2)² = 3.14 * 9² = 3.14 * 81 = 254.34 in²
Circumference of a circle = 2 π r
30 = 2 * 3.14 * r
r = 30 / (2*3.14) = 30 / 6.28 = 4.78 inches
Standard basketball = 3.14 * (4.78)² = 3.14 * 22.85 = 71.75 in²
254.34 - 71.75 = 182.59 in²

Parameter of Statistic
From the question, we understand that the teacher is to calculate the class average.
To calculate the class average, the teacher will use the mean function/formula, which is calculated as:

Generally, mean is an example of a parameter.
<em>So, we can conclude that the teacher will use parameer</em>
I would think miles per hour would be the best units to use because that is what the speedometer of a car is read in. Hope this helped! comment back with any questions you still have!
Answer:
254.34
Step-by-step explanation:
This is because A=C2
4π which is 18x18 divided 4x 3.14 which equals 254.34
