The diameter of a quarter is about 6 cm. Find the area of the quarter. Use 3.14 for π
If the diameter is 6 cm then the radius is 3 cm. Area of a circle is A = πr2
substituting values A = (3.14) x (3 cm)2 = 3.14 x 9 cm2 = 28.26 cm2

THAT is a really BIG quarter ! 2.4 inches in diameter....
The quarter is for giants, not us.
