Circumference of the circle: 63 times pi = 198 mm rounded to the nearest integer
2 times pi is not an integer. Since Pi is an irrational number, 2 pi is also an irrational number.
If n is any integer, then (n/pi) times pi is a whole number.
Using 3.14 as Pi the area of circle is: 94.985
Area: pi times 50 squared = 7854 square cm rounded to the nearest integer
Area = pi*r2 = 3217 sq inches to the nearest integer.
Radius = 540/2*pi = 86 rounded to the nearest integer
Radius: 201.1/(2*pi) = 32 units to the nearest integer
If you mean pi then: 50 times pi is about 157 to the nearest whole number
It is: pi*2.252 = 16 square feet rounded to the nearest integer
Another answer:- Total area of circle: 360/190 times 662.89/1 = 1256 rounded to the nearest integer Radius of the circle = square root of 1256/pi = 20 rounded to the nearest integer
pi is not a integer any of the natural numbers (positive or negative) or zero; "an integer is a number that is not a fraction"- since pi has a decimal it isn't considered a integer
