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

Answer:
6 cm²
Step-by-step explanation:
Since 3 side lengths are given, I assume that this figure is a triangle. The area of a triangle can be determined by using hero's formula.
⇒ s = Perimeter/2
⇒ a, b, and c = side lenths of triangle
<u>Replacing a, b, and c as the given side lengths:</u>
<u>Determining the perimeter of the triangle:</u>
<u>Determining the half of perimeter:</u>
<u>Replacing the value of "s" in the formula:</u>
<u>Evaluating the area:</u>
