The nearest whole number the diameter of the circle is 5.0 cm.
<u>Given the following data:</u>
- Circumference of a circle = 15.4 cm
To estimate to the nearest whole number the diameter of the circle:
In this exercise, you're required to solve for the diameter of a circle and round up its value to the nearest whole number.
<h3>How to calculate the circumference of a circle.</h3>
Mathematically, the circumference of a circle is given by the formula:

<u>Where:</u>
- D is the diameter of a circle.
Making D the subject of formula, we have:

Substituting the given parameters into the formula, we have;

D = 4.90 cm
To the nearest whole number:
D = 4.90 ≈ 5.0 cm
