Okay. I am attaching an image for number 25. Now for number 26, the possibilities with this question are endless...lol. Pi is an irrational number and the easiest, for me anyway, to give two real-life examples.

I needed my son to install a circular light fixture, so of course, we needed to figure the circumference of the. We use pi (3.14) with r as the radius.

The second example would be the speedometer of a car. Pi is used to determine the calibration needed. 

I hope these help.

Take care, 
Diana

The table shows the height, in centimeters, that a weight bouncing from a spring would achieve if there were no friction, for a
Paha777 [63]
Hello! For ease of calculations, we can identify the time it took for the weight to bounce back to the other direction, then the other, and then back to its original position by looking at the time it took for the weight to change from 0 to 25 to 0 to -25 then back to 0. This is one whole cycle of the weight.

By the time the weight first reached zero, 1.5 seconds has passed. By the third time it got to zero again, 7.5 seconds has passed. Therefore, one whole cycle of the weight is 7.5-1.5 = 6.0 seconds.

ANSWER: One whole cycle of the weight took 6 seconds.
