Area, Diameter, Radius and Circumference!
In math we have learned about stuff that may look like gibberish to but in the end it makes a lot of sense. One example is how pie = 3.14 and how D times 3.14 = C. That probably made no sense to you did it. Well heres what i did. Pie is 3.14 as showed at the top, the "D" is diameter. So to get the circumference or "C" you have to multiply "D" and pie in the end you will get C! Here is some more math that we have
