Question

Kaye will compute for the area of a circle using the formula A=π×r2.If given is the diameter of a circle , what should be computed first?

​

Answer 1

Find the radius.

Explanation:

The task is to solve for area of a circle, and you are given the diameter.

The formula for area is :

Area of a circle = π × (radius)²

In this formula, there is only one input value, and that is the radius.

To find the radius, you must know the relation :

Radius x 2 = Diameter

Hence, the radius must be computed first and foremost.
