The diameter of a bacterial spiral is 1.5 x 10-5meters.
The area is 28.274 square meters.
The American penny is 19 millimeters in diameter, and a meter stick is 1,000 millimeters....so if we divide 1000 by 19, we find that 52.63 pennies would run the length of a meter stick.
The diameter is a straight line going from a point on the circumference of a circle, through the centre of the circle, to another point on the circumference. It can be of any length. A metre is a standard unit for measuring length.
