Infinity is not a number. It is the idea that for every number that exists, there exists a number greater than that. Therefore, asking the question "What number comes after infinity" is like asking "Where is the corner of the Earth". Since the Earth has no corners, the question is meaningless, as is yours.
In general, you cannot. An infinite number divided by any non-zero number is still infinite. An infinite number divided by another infinite number may or may not be infinite.
It is infinite.
If you mean the number pi, that has an infinite number of decimals.If you mean the number pi, that has an infinite number of decimals.If you mean the number pi, that has an infinite number of decimals.If you mean the number pi, that has an infinite number of decimals.
Each integer has a finite number of factors and an infinite number of multiples.
How about 1 and 149. There are an infinite number of pairs, an infinite number of triplets, an infinite number of quadruplets, ... an infinite number of n-tuples. And n, itself, can be infinitely large.
NO because there is an infinite number of them, just like there is an infinite number of primes. In fact, if there is an infinite number of primes there must be an infinite number of composite numbers too... do you see why?
A infinite number is a number that goes on forever.
Pi is an irrational number. As such, it has an infinite number of digits.
The radius of a circle or a sphere has infinite number of points.
An infinite number, because there are an infinite number of slopes with an infinite number of y-intercepts.
There will be 1 circle, 1 square, an infinite number of ellipses, an infinite number of rectangles, an infinite number of other quadrilaterals, an infinite number of polygons with 5 or more sides, an infinite number of odd shapes. In all, a lot.
If you mean "the last number", there is no such thing; you can always add one more. Even infinite numbers - numbers that describe the magnitude of infinite sets - don't have a "last number"; you can always find a larger infinite number. Specifically, if you have a certain infinite number, 2 to the power of that infinite number will give you a larger infinity.
