Which of the following is the best approximation of the circumference of a bicycle wheel whose diameter is 26 centimeters? 82 cm
163 cm
531 cm
2,123 cm

82 cm

Step-by-step explanation:

Circumference is pi times diameter. A common value of pi is 3.14.

So the number we should choose is a little more than 3× 26 = 78.

82cm is the answer that works.

median is the value separating the higher half of a data sample, a population or probablity distribution from the lower half.

step-by-step explanation:

say you have 3,8,7,3,1,9,8 order them from lowest to highest

if orderd it would be 1,3,3,7,8,8,9 now you take away from the lowest and the highest until you end up in the middle.

so you would remove the 1 and 9 leaving you with 5 digits remaining

when you've reached the middle that would be your answer so in this case the answer is 7

if there were two numbers left say 7 and 5 you'd and them together so 12 then divide by 2 witch would equal 6 so the answer would be 6

good luck on that project hoped i you at all

good luck on your studies! : )
