The answer depends on the value of W.
The first 55 digits of pi after the decimal point are: 3.1415926535897932384626433832795028841971693993751058209
Pi to 144 decimal places is written thus: 3.14159265358979323846264338327950288419716939937510 58209749445923078164062862089986280348253421170679 82148086513282306647093844609550582231725359 The sum of these first 144 decimal digits (after the decimal point) is 666.
The first occurrence of the digit 0 in the digits of pi is at the 32nd decimal place.
3.1415
3.1415
They are 14159265358979323846
Not including the initial digit, the first 23 decimal digits of pi are 3.14159265358979323846264.
You need to add up the number of digits to the right of the decimal to find the number of digits in the answer. If the first factor has 2 digits to the right of the decimal point and the second factor has 3, the final answer will have 5 digits to the right of the decimal point.
One way is to multiply the numbers ignoring the decimal point. If the first multiplicand has d1 digits after the decimal point, and the second has d2 digits after the decimal point, then their product has (d1 + d2) digits after the decimal point.An alternative for the second stage is to estimate the answer to determine where the decimal point should go.
A percentage of a number equates to that quantity of hundredths of that number. A number of hundredths when expressed as two digits, are the first two figures after (to the right of) the decimal point. EXAMPLE : 80% of 65 is equal to 65 x 80/100 = 52 BUT, 80/100 expressed in decimal form is 0.80. The calculation could then be written as 65 x 0.80 = 52
* Remove trailing zeros now you have 789 Insert a decimal point between the first and second digits now you have 7.89 Count the digits to the left of the first digit in this case 10 Multiply the number in step 2 by 10 raised to the power the number in the third step So you get 7.89 X 1010 It can also be expressed as 7.89E10
First there's the 3 before the decimal point, and then, after the decimal point, comes 14159 26535 8979.
