I believe it's 19. No more than 24, for sure.
No. Area of 3 inch circle is 9/4 pi so two of them total 9/2 ie 4.5 pi. Area of 6 inch circle is 9 pi, the equivalent of 4 of the smaller circles!
The circumference of a 4 inch round circle is: about 12.57 inches. You can easily do this calculation for other circles by multiplying the diameter by Pi (about 3.1416).

A four-inch radius circle has an area of about 50.27 square inches.
The circumference of a 10 and a half inch circle is about 33 inches (32.99). (C = d x Pi)
Make circle with 18 inch radius, fold in half, fold in half.
The circumference of a 4 inch round circle is: about 12.57 inches. You can easily do this calculation for other circles by multiplying the diameter by Pi (about 3.1416).
Area of a circle = pi*radius2
The circumference of a 13 inch round circle is: about 40.84 inches.To do this calculation for other circles, just multiply the diameter by Pi (about 3.1416). The result is the circumference.
