Robo - friends
We have a ROBO-FRIEND that we call mYρ Botic, it is a word’s game in Serbian made with English and Greek letters. Our team is from Technical High School “23. may”, located in Pancevo! Our ages are between 18 and 19, but because we're all year 4, you can say 18. We love making robots, they are fun and easy to make! Our mYρ is made out of 3 basic shapes: Circles, Squares and Rectangles. Their body is mostly made out of Squares and Rectangles, but his hands, eyes, circuits and antenna are made out of Circles. Chosen power: helping people at oil wells with measuring flow of fluids in oil transportation. Because, working on oil wells is a very dangerous job, it is really helpful if robots can replace us humans in this dangerous part of our work. Our ROBO-FRIEND needs to learn the basics of measuring fluid flow, which is basically measuring flow rate of liquid, gas or steam in pipes because they are used for transporting. He also needs to learn where oils and gasses get extracted and how they get transported to facilities Our mYρ has gained a lot of recognition and has been adored by the people that have seen him and that have heard his story. They say he’s been a huge help with the oil wells as well so they say that he’s also a smart one. Here is some interesting things we all have to learn to help our ROBO?FRIEND [b]mYρ[/b] to work.

Rectangle Area
Rectangle Area
In order to understand the formula for the rectangle area, we have to explore the following structure. [br](ps.: this structure was modified from the one made by Jayrton Carvalho)
Analysis 1
Move the bar and look as the rectangle is filled. How many little squares can fit in the rectangle?
Analysis 2
Change the base (B) measure to 10 and the height (H) to 5. Move the bar and look as the rectangle is filled. [br]How many little squares can fit in the rectangle?
Analysis 3
What is the connection between the number of little squares (n) that fit in the rectangle with the height (H) and the base (B) of the rectangle? [br]
Analysis 4
In theory, the number of small squares that fit in the rectangle can be considered the area of the rectangle.[br]Thus, write an equation that represents the area of a rectangle of base B and height H. [br]
What if this little square was smaller?

Bourke High School - Area of a circle
This animation demonstrates the area of a circle is equivalent to the area of the corresponding rectangle having the side dimensions of [math]r[/math] and [math]2\pi r[/math]. Move the black dot from left to right to 'explode' the circle into a rectangle.[br][br]The animation should prompt you to recall or derive the formula for the area of a circle (if in doubt, move the hint black dot from left to right).
Animation for the area of a circle
Investigation:[br]1) Move the slider above the circle and describe what happens to the circle step by step.[br]2) Make a conjecture about the formula for the area of a circle and show how you develope this formula. (move the slider named hint to help you)
