Ten Trillions. Note: One followed by Three zeros = 1 Thousand One followed by Six zeros = 1 Million One followed by Nine zeros = 1 Billion One followed by Twelve zeros = 1 Trillion One followed by Thirteen zeros = 10 Trillions
It has 4 significant figures.Significant Figuresà Non-zero numbers are always significant figures.à Zeros are tricky:- If zeros appear before a non-zero (called leading zeros), they are NEVER significant (ex: 0.025)- If zeros fall between non-zero numbers, they are ALWAYS significant (ex: 205)- If zeros come at the end of the number, they WILL be significant only IF there is a decimal present (ex: 250.0)à Exact numbers (or counting numbers) have infinite significant figures. For example, if we count 3 pencils, we know there are exactly 3 pencils. Or, when we say 1 inch = 2.54 cm, we know this is for exactly 1 inch.
I assume you mean compared to a metre. A millimetre is 0.001 metres. This is because milli means 1/1000.
Less digits are needed but they still have the same numerical values.
significant figures are digits of certainty. In other words they are exact numbers. Except zeros are placeholders (not exact) unless if they are in between non zeros. Also zeros at the end of numbers are significant figures if there is a decimal point.
