how many centimeters in a 100 yards

Question

need help to calculate the answer for this question by showing all the necessary calculations involved for this problem listed

Answer 1

 1 inch = 2.54 cm

 

  1 yard  * 3ft/ 1yrd * 3 ft * 12in / 1ft * 36 in * 2.54 cm/1 inch = 91.44 cm 

   

      0.91 meter.

 

  100 Yrd = 100 * 91.44cm = 9144 cm

Answer 2

Everyone knows that the meter's length is rigorously defined. There used to be a platinum bar in Paris with two lines scribed on it that defined the meter. Now I think they use wavelengths of light.

But did you know that the English system of inches, feet, yards, etc., is just as rigorously defined? It is, because the inch is defined to contain EXACTLY 2.54 centimeters.

(100 yards)(3 feet/yard)(12 inches/foot)(2.54 cm/in)

= 9144 centimeters, exactly.

Answer 3

Another way to look at the problem:

100 yards=300 feet=3600 inches

1 meter=39.37 inches

3600/39.37=91.44018 meters

100 yards=91.44018 meters

1 meter=100 centimeters

91.44018*100=9144.018 centimeters in 100 yards

Answer 4

Start with the conversion

 

1ft = 30.48cm

 

if we divide both sides by 30.48cm we can see that

 

30.48cm/1ft = 1

 

similarly, for yards to feet

 

1yard = 3ft

 

and dividing by 1 yard we get

 

3ft/1yard = 1

 

Now, we have 100 yards and want to find out how many cm this is equivalent to.  Lets convert the units. If we multiply by something by 1, we do not change the value

 

100yards = 100yards*1

 

but since we know

 

1 = 3ft/1yard

 

we can do

 

100yards = 100yards*(3ft/1yard)

 

100yards = 300ft

 

Now, to convert 300ft to cm, multiply by 1 in a similar way.

 

300ft = 300ft*1

 

and we know

 

1 = 30.48cm/1ft

 

so

 

300ft = 300ft*1 = 300ft*(30.48cm/1ft)

 

300ft = 9144cm

 

9144cm in 300ft, and therefore 9144cm in 100 yards.
