4 0

Πd = C.

The ratio of circumference to diameter is a fixed constant. No matter how large or how small the circle, the ratio of its circumference to diameter is always just a little over 3. 3.14 to be more accurate, sometimes approximated by 22/7.

To be more precise, the value is: 3.1415926535... and never repeats or terminates. The letter used to represent this value is the Greek letter "pi" which is pronounced "pie."

Ann made a 33-step staircase using 1818 toothpicks as shown in the figure. How many toothpicks does she need to add to complete

malfutka [58]

You would take 1818÷33=55.09

55.09 is how many toothpicks it took for each step made

Then you would take 55.09×55=3029.95

You can make sure this is correct by taking 55.09×33=1817.97 which would actually be 1818 because you had to round it up
