The formula for the Circumference of a circle is 2•Pi•R, or 2•Radius•3.14
This is to calculate the measurements around the circle.
The formula for the Area of a circle is Pi•R^2, or 3.14•R•R
This is to calculate the entire circle.
I hope this helps!
For this problem,we use the Fundamental Counting Principle. You know that there are 7 digits in a number. In this principle, you have to multiply the possible numbers for every digit. If the first number cannot be zero, then there are 9 possible numbers. So, the value for the first digit is 9. The second digit could be any number but less of 1 because it was used in the 1st digit. So, that would be 10 - 1 = 9. The third digit must be the value in the second digit less than 1. That would be 9 - 1 = 8. And so on and so forth. The solution would be:
9×9×8×7×6×5×4 = 544,320 7-digit numbers
Answer:
3 hours: 38,250
1 day: 122,440
I’m not sure if this is exactly right, my brain gave out half way. Someone check my answer pls
Step-by-step explanation:
3 hours: 3 x 60= 900
900 divided by 20= 450
450 x 85 = 38,250
1 day: 24 x 60 = 1440
1440 x 85 = 122,440
hope it will help u......
