How do you find a circumference of a circle if the radius is a fraction?
The circumference is 2*pi*radius. It does not matter if the radius is an integer or a fraction.The circumference is 2*pi*radius.

Is 22 over 7 a rational number?
Yes. A rational number is defined as any integer divided by any (nonzero) integer, so 22/7 is rational.You're probably asking because some people say that Pi is equal to 22/7 (I also remember being told this once as a kid). This is false. The constant Pi is an irrational number, which means that it cannot be expressed exactly as one integer divided by another integer, or as a finite decimal expansion. 22/7 is a close approximation of Pi, to about three digits, but it does not equal Pi.
What times pi is a whole number?
If n is any integer, then (n/pi) times pi is a whole number.
What is the measurement for which the sine is at its maximum?
It is pi/2 + 2*k*pi radians for integer k.
What are some examples of a fraction but not a rational number?
A rational number is a fraction with an integer in the numerator, and a non-zero integer in the denominator. If you consider pi/2, pi/3, pi/4 (common 'fractions' of pi used in trigonometry) to be 'fractions', then these are not rational numbers.
Is pi an 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
2pi is an integer?
2 times pi is not an integer. Since Pi is an irrational number, 2 pi is also an irrational number.
Can pi be written as a fraction?
22/7 I think is the closest fraction you will get. By definition it is irrational, and cannot be written as fraction of integer numbers. There are a few fractions that are close approximates though. Pi cannot be technically written as a fraction. However, a fraction that is a close approximation of pi is 22/7.

What is pi times pi to the nearest integer?
π 2 = π x π = approx. 9.86, the nearest integer is 10.

Is pi a composite number?
No. The concept of composite is applicable to integers. Pi is not an integer.
What times pi is a whole number?
If n is any integer, then (n/pi) times pi is a whole number.
Why pi is not a surd?
A surd is the square root of an integer (whole number), e.g. square root of 2 is a surd. Pi is not the square root of an integer so not a surd, just an irrational number
What is the measurement for which the sine is at its maximum?
It is pi/2 + 2*k*pi radians for integer k.

What number that is a negative but not integer?
-1.5, -pi, -2/5
