Where are the denominator and numerator located in a fraction?

For this case, we have to, by definition:

The numerator: Is the number that, in a fraction, indicates the equal parts of the unit that contains that fraction. It is located at the top of the fraction.

The denominator: It is the number that, in a fraction, indicates the equal parts in which the unit is considered divided. It is at the bottom.

Example:

Let the fraction

The numerator is "a" and the denominator is "b".

Numerator: Top

Denominator: Bottom

256π units²   (answer b)

step-by-step explanation:

the formula for the surface area of a sphere of radius r

is             a = 4πr²

and so, if r = 8 units, then the surface area is:

a = 4π(8 units)² = 256π units²   (answer b)

the correct is answer is a 9-sided polygon!
