Math week 8

In week 8 term 3 my math group with Nicole, The Humans we were looking at the circumference of a circle. some of the tasks we did were around finding the area of circles using the radius and diameter. The formula for calculating the circumference of a circle is Pi rx2 and the formula for finding the are of a circle is pi r2. The most challenging slide was the one where we had to prove why the perimeter of the circle is smaller than any other shape. My favourite slide was finding the area of the circle using the diameter.
