the radius of a nickel is 1centermeter. if 10 nickles are placed in a row, how long will the row be?
20 cm
The diameter of a nickel can be determined by multiplying the radius by 2. Therefore, the diameter of a nickel is 2 centimeters.
To calculate the length of the row with 10 nickels, we need to consider that there will be a small gap between each nickel. Since the diameter of one nickel is 2 centimeters, the total length of 10 nickels will be 10 times the diameter plus 9 times the gap.
The total length can be calculated as follows:
Total length = (10 nickels) x (diameter) + (9 gaps)
= (10 nickels) x (2 centimeters) + (9 gaps)
= 20 centimeters + (9 gaps)
Since the gap is not provided, we cannot calculate the exact length of the row. However, we know that the length of the row will be longer than 20 centimeters due to the added gap between each nickel.
To find the length of the row, we need to calculate the total diameter of 10 nickels and then convert it to length. Here's how you can do it:
1. Find the diameter of a nickel:
- The radius of a nickel is given as 1 centimeter.
- Diameter is twice the radius, so the diameter of a nickel is 2 centimeters.
2. Calculate the total diameter of 10 nickels:
- Since each nickel has a diameter of 2 centimeters, multiply that by the number of nickels in the row (10).
- 2 centimeters x 10 nickels = 20 centimeters.
3. Convert the total diameter into length:
- Since the row is a straight line, the length will be equal to the total diameter.
- Therefore, the length of the row will also be 20 centimeters.
So, the row of 10 nickels will be 20 centimeters long.
The radius is half the diameter.
