Please help explanation if possible

18.84 feet.  let me know if you have ay other questions.

Step-by-step explanation:

The way to find the formula for circumference is kinda complicated so it is best to ust memorize the formula, which is 2πr.  or 2 times pi times the radius.  

Your problem gives you the formula, but instead of 2 and r in it you have d, which is the diameter.

The diameter of the circle is 2 times the radius, so that's why it is replaced.

the radius is the distance from the center fo the circle to one edge, and the diameter is the distance through the circle passing through its center.  so it's the center to one end plus the center to another end.  or r+r which is also 2r.

So d = 2r, so in this problem d =6 feet.

So now the formula πd = 3.14*6 feet = 18.84 feet

The Median will be 89

In order to find the median we first put the data in ascending form which will be 79,80,86,92,95,96

Then we find the middle number in case the data is odd. Since the data is even in our case so we will find the average of the middle two which are 86 and 92

So (86+92)/2 = 89

So the median is 89
