19.63 square inches are in the area of a 5-inch diameter circle.
Area of circle: pi*1.25^2 = 5 square inches rounded to the nearest whole number
There are 100*pi square inches in a 20 inch diameter circle
Circumference of circle: 31.4 inchesArea of circle: 78.5 square inches
Area of circle using 3.14 for pi: 3.14*5^2 = 78.5 square inches
