Why is a quarter approximatly 2 mm thick?
It is, in fact, 1.75 mm thick, not 2 mm. So any reasons which tried to explain why it is 2 mm thick would be contradicted by reality!
Area of a quarter?
A US quarter is 24.26 mm in diameter, giving it an area on each face of 462.2441 square mm (A = pi * r^2). Is also 1.75 mm thick, meaning that the edge (assuming that it was smooth - that is, without giving effect to the increase area brought about by the 119 reeds on the reeded edge) would have an area of 133.3763 square mm (A = 2 * pi * r * h). Thus, the total surface area of a US quarter would be 1057.8645 square mm. A Canadian quarter is 23.81 mm in diameter, giving it an area on each face of 445.2548 square mm (A = pi * r^2). Is also 1.60 mm thick, meaning that the edge (assuming that it was smooth - that is, without giving effect to the increase area brought about by the reeds on the reeded edge) would have an area of 119.6821 square mm (A = 2 * pi * r * h). Thus, the total surface area of a Canadian quarter would be 1010.1916 square mm.
What is the circumference of a quarter?
The diameter of a quarter is 24.26 mm. Circumference is pi* diameter. 24.26 mm * 3.14159=76.21 mm
What is the area of quarter pi is 3.14 and the diameter is 4 mm?
Would be the area of a circle.Area = pi * radius squaredA = pi*r2radius = diameter/2Radius = 4 mm/2 = 2 mmArea of quarter = (3.14)(2 mm)2= 12.6 mm2========
Which is bigger 1.5 mm or 7 mm?
7 mm, because 1.5 is less than 2, while 7.0 is greater than 2. Don't let decimal points fool you!
