1 meter = 100 cm 1 cm = .01 meters
C = πd80 = πd80/π cm = d25.46 = d (decimal approximation)25.46 / 2 = r12.73 cm = r (decimal approximation)
hi 35 cm is 0.35 metres because 35 cm is less than 1 metre we have to write it as a decimal after the zero and the decimal point.
Example: 100 cm = 1 m 1 cm = 0.01 m You have to change the decimal by two places depending on whether you are going from cm to m, which would be two places to left, or m to cm, which would be two places to the right.
Circumference of circle: 15*pi = 47.124 cm rounded to 3 decimal places Area of circle: pi*7.5 squared = 176.715 square cm rounded to 3 decimal places
3.5 cm, you move the decimal
.05 cm
1 meter = 100 cm 1 cm = .01 meters
By unit of length and distance and conversion ,we can say that four cm is written in decimal as 4.00 cm
C = πd80 = πd80/π cm = d25.46 = d (decimal approximation)25.46 / 2 = r12.73 cm = r (decimal approximation)
hi 35 cm is 0.35 metres because 35 cm is less than 1 metre we have to write it as a decimal after the zero and the decimal point.
12.0 cm
13.15 times 13.15 = 172.92 square cm rounded to two decimal places
4 cm, exactly as in the question. A decimal number is simply a way of representing a number in such a way that the place value of each digit is ten times that of the digit to its right. A decimal representation does not require a decimal point.
Example: 100 cm = 1 m 1 cm = 0.01 m You have to change the decimal by two places depending on whether you are going from cm to m, which would be two places to left, or m to cm, which would be two places to the right.
