the area of a penny is 2.8338cm2
Well, honey, a penny has a diameter of about 0.75 inches, so we can calculate the surface area using the formula for the area of a circle. The surface area of a penny is approximately 0.441 square inches. So, there you have it, the glamorous surface area of a humble little penny.
You can get a stack of pennies, measure the height of the stack and then divide by the number of pennies. You can also get the thickness by treating the penny as a cylinder, calculating the area of the face of the penny, then putting a whole lot of them in water, measuring the change of volume to get the total volume of all pennies, then divide by the number of pennies and divide again by the area of the penny to get the thickness.
