_unit(s)

explan to me because i dont understand this.

Diameter =  units

Step-by-step explanation:

There are 2 formulas that we have for circumference of a circle, shown below.

This comes from the fact that twice radius (r) is equal to diameter (d).

Since the question asks for diameter given circumference, we will use #2 formula from above because it relates circumference and diameter.

C = T [given]

d = ???

Let's find by substituting in formula:

Hence the diameter is    units

15.0 is a

Natural Number - It is a counting number.

Whole Number - it is also counting number not including 0.

Integer - it follows the rules of an integer.

Rational Number - it can be expressed as a fraction.

Therefore your answer is ALL OF THE ABOVE
