Jon and Becky measured the circle shaped part of a sun they drew on the sidewalk. The diameter of the circle is 53 centimeters. What is the approximate area of circle? ( use 3.14)
To find the area, we use the formula A=pir², where pi=3.14 and r= the radius.
To solve, we find half of the diameter, which is the radius. Half of 53 is 26.5. We square this number and then multiply it by pi. 26.5·26.5=702.25. Now we multiply by pi. 702.25·3.14=2,205.065.
