# How “Car Park” is Related to the Statement of Inquiry

Statement of Inquiry: Algebra makes our world more efficient

Today we did an activity on Desmos and we tried to combine algebra equations into real-life situations. We basically need to put car park dividers in a car park space but having an equal amount of space for each car to park in. In this situation, we used letters as algebra representatives and we are trying to use this formula created and make sure it works in any situation based on the car park. It’s related to the statement of inquiry because we used these formulas and it can make us calculate the spaces in a quicker and more accurate way. Although this situation is online, we can apply it in real life and apply the equation as well.

I think the bestÂ activity we did in this unit is the circle estimation project. For the project, we have a list of procedures for different ways to estimate a circle’s area. The first one is dividing the circle into 8 equal parts, and putting these 8 parts to a close parallelogram. Then, we timed the the length and the height of the parallelogram and then assume that’s a close result of the original circle’s area. The second procedure is turning a circle into an octagon. We drew lines on the original circle to form a close octagon and calculate the area of hat so it will be close to the circle’s area. The third procedure is putting beans on the circle to fill the whole thing. After that, you collect all the beans that filled the circle into a rectangular. For the rectangular, you will need to measure the length and height for the space that’s covered with beans so we know the area of the circles. From this experience, I learned the different ways of measuring the circle’s area and also knowing where did the formula for calculating a circle’s area come from. Here are some photos:
