What is the circumference of a nickel in cm?
US nickels have a diameter of 21.21 mm. The formula for a circumference is pi x D where D is the diameter. For a nickel that's 21.21 x 3.14159 = 66.63 mm. Divide by 10 and you get 6.663 cm.
What measurement do you use to measure a coin?
well it depends. The material coins are made of is different. Nickel or copper. Therefore pounds. OR The circumference. Diameter X Pi.(3.141...).
What is the surface area of a nickel?
The Surface Area of a Sphere = 4pi r 2I believe this formula is the same for a nickel, as a nickel falls into the "circle" or "sphere" category.Actually it is the formula 2B+Ch because the nickel is technically a cylinder that is really short so it uses the cylinder formula and NOT the sphere formula.B is the area of the base or a face of the nickel. Doubling it counts for the other base and C is the circumference of the base. h is the height of the whole thing. A nickel's surface area is (2)(3.14)(1.052)+(3.14)(2.1)(0.15). Figure out the rest yourself.

If the diameter of a nickel is 21 millimeters what is the circumference?
To find the circumference of the nickel, you can use the formula C=πd. Where C is the circumference and d is the diameter. π is a special constant with a value approximately equal to 3.14. Substituting your numbers into the equation gives you C≈3.14(21) or C=65.94 square mm.

What is the circumference of a loonie?
A circumference is 4
Is the radius one fourth of the circumference?
No. It is circumference/(2*pi)No. It is circumference/(2*pi)No. It is circumference/(2*pi)No. It is circumference/(2*pi)
Why is circumference equal to 2 times Pi times r?
Circumference = pi times diameter or Circumference= two x pi x radius. Now remember the diameter of a circle is the straight line from one edge of the circle, through the centre to the opposite edge. The straight line from the edge to the centre is the radius, and then from the centre to the opposite edge is another radius. So the diameter is the length of two radii. Algebraically express as d = 2r. So Algebraically C = pi*d Substituting the 'd' for '2r' C = pi2r However in algebra coefficient numbers are expressed to the left. Hence C = 2pir Why 'C' is this expression I would have to go into some 'very heavy' differential calculus. Suffice it to say, the ancients found that the circumference traced by a donkey/mule driving water out of well was directly proportional to the diameter, twice the length of the tether(2 radii). From this they discovered that for however long the the tether and the circumference were. they had a constant of proportion C directly related to diameter. This is equated to C = kd And k = C/d , which was founf to be 3.141592..... which now call 'pi'. for any sized circle. So today in school you learn C = pi d or C = 2 pi r And for circular area(A) A = pi r^(2) The 'pi' youare given in school is proabably 3.14 , 3.1416 or 22/7 . However, these values are Approximatons, because 'pi' is an irrational number. Hope that helps!!!!!!
