The circumference is about 6.28 (2 pi) inches.
This is just addition of the thickness of two opposite walls (1/4" x 2 = 1/2) to the inside diameter (1 1/2 + 1/2 =2), then multiplied by pi.
A U.S. quarter has a diameter of 2.425 centimeters. This measurement reflects the width of the coin across its circular edge.
The moon's diameter is 3,474km (approximately a little more than one-quarter of the Earth's size). The earth's diameter is 12,742km.
There are 25.4 millimetres in an inch. Therefore a millimetre is 0.03937 inches. To find out how many quarter inches are in a millimetre, you'd multiply by 4 as there are 4 quarters in a unit. 0.03937*4 is 0.1575 quarter inches in a millimetre.
To estimate the size of the cell occupying one quarter of the field of view, first determine the diameter of the field at high magnification from your lab activity. If the diameter is, for example, 400 micrometers, then the area of the entire field is approximately 125,600 square micrometers (using the formula for the area of a circle: A = πr²). Since the cell occupies one quarter of this area, its area would be about 31,400 square micrometers. To find the approximate diameter of the cell, you can rearrange the area formula (A = πr²) to solve for r, and then multiply by 2 to find the diameter.
Thickness is measured in units of length. You'd have to choose the one that gives a reasonable number corresponding to whatever you're measuring the thickness of. If it's the thickness of a hair, you'd probably select a sub-multiple of a meter. If it's the thickness of the atmosphere, you might select the kilometer. If it's the thickness of country gravy, that's a whole different story.
Diameter: 24.26 mm Circumference: 76.215 mm
The diameter of a quarter is 24.26 mm. Circumference is pi* diameter. 24.26 mm * 3.14159=76.21 mm
The diameter of a quarter is 24.26 mm. Circumference is pi* diameter. 24.26 mm * 3.14159=76.21 mm
The diameter of a quarter is 24.26 mm. Circumference is pi* diameter. 24.26 mm * 3.14159=76.21 mm
radius = diameter / 2 The thickness is irrelevant.
A US quarter has a diameter of 0.955 inches (24.26 mm) and a thickness of 0.069 inches (1.75 mm). Its circumference can be calculated using the formula for the circumference of a circle (C = πd), which gives it a circumference of approximately 3 inches (7.62 cm).
AUS. quarter is 24.26 mm in diameter. Multiply by pi to get the circumference.(second person) what is the answer stupid!
The diameter is 24.3mm and thickness is 1.75mm.

Circumference = (4) x (a quarter of a circle) = (pi) x (the diameter)Diameter = (4 x quarter-circle) divided by (pi)Radius = 1/2 the diameter = (2 x quarter-circle) divided by (pi)
pi = 3.14 (approx) diameter = width of a circle pi x diameter divided by 4
easy pi 3.141592654 or 3.14 times the diameter then divide by four first you find the entire circumference then cut into halves or quarters
