If a stack of 40 nickels fits snugly in the coin wrapper shown, how thick is 1 nickel? Round to the nearest hundredth.

Question:

If a stack of 40 nickels fits snugly in the coin wrapper shown, how thick is 1 nickel? Round to the nearest hundredth.

Coin wrapper volume = 27,480 mm^3

Coin diameter = 21.18 mm

The thickness of a coin is: 1.95mm

Step-by-step explanation:

Given

-- volume

--- the diameter

Required

The thickness of each coin

This implies that, we calculate the height of each coin.

First, calculate the radius (r) of the coin

The volume of the coin is calculated as:

Where H represents the total heights of the 40 coins

Solve for H

The height of a coin is calculated by dividing H by 40

Hence, the thickness of a coin is: 1.95mm

good luck!
