RafaThe formula for the cross-sectional area of a coin is calculated using the formula for the area of a circle, which is A = πr^2. In this formula, A represents the area, π is a constant approximately equal to 3.14159, and r is the radius of the coin. By substituting the radius of the coin into the formula, you can calculate the cross-sectional area of the coin.

What is the formula for the volume of a quarter coin?
Coins are not cylinders. The rim of the coin is sometimes raised, as well there are depressions and peaks from the design of the coin. You should use a specific gravity test with water and a scale. bullionultrasound shows how to measure the volume of an American Gold Eagle coin using the specific gravity method, how to calculate density, etc... it's pretty informative. According to The United states Mint website, a US quarter is 24.26 mm in diameter and the thickness of the coin is 1.75 millimeters. To find the area of a circle the formula is pi*r^2 so the face of a quarter has an area of pi*(24.26/2)2 = 462.244204 mm2. To then find the volume we multiple the area of the face by the thickness, so the volume is 462.244204 * 1.75 or pi * (24.26/2)2 * 1.75= 808.927357mm3. So the volume of a us quarter is about 808.93 mm3. This does not take into account the ridging on the edge of the coin or the printing on the face.
How do you get volume of the coin?
Think of the coin as a cylinder. The volume is the area of the base X the height. The area of the base is Pi X radius squared. So if you know the radius or the diameter of the coin, which you can measure, and the height which you can also measure, than PiXr2Xh will give you the volume.
Circumference of an Australian 1 Dollar?
The circumference of an Australian 1 Dollar coin is approximately 25.00 mm. This measurement is based on the standard diameter of the coin, which is 25.00 mm. The circumference of a circle can be calculated using the formula C = πd, where C is the circumference, π is the mathematical constant pi (approximately 3.14159), and d is the diameter of the circle.
