Best Answer

The diameter of a nickel is 2.121 cm.

To find the perimeter of the nickel, we will use the equation 2(Pi)r

To find the radius, r, divide the diameter by 2.

2.121/2=1.0605

P = 2(3.14159)(1.0605)

= 6.6633 cm

Therefore, the perimeter of a nickel is approximately 6.66 cm.

How many nickels are in one inch?

Assume that nickels are measured in diameter, and we want to form the certain number of nickels to form an inch. Let the diameter of the nickel be 22 millimeters, which is 2.2 centimeters. Note that 1 inch = 2.54 centimeters. Then, there is no definite number of nickels that exactly form an inch since: 2.54 centimeters * 1 nickel / 2.2 centimeters = 1.15... nickels [and we obtain the "incomplete" nickel to form an inch]!

What does it mean to measure something to the nearest whole decimetre?

Meter sticks usually have marks for centimeters, not decimeters, so in this case, you could take the measurement to centimeters, then round. For instance, if the measurement is 53.8 centimeters, you round this to the nearest 10 centimeters (50), then convert to decimeters (5).Meter sticks usually have marks for centimeters, not decimeters, so in this case, you could take the measurement to centimeters, then round.
