If the circumference of a circle is about 15.4 cm, estimate to the nearest whole number the diameter of the circle
nasty-shy [4]

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:

Circumference = \pi D

<u>Where:</u>

  • D is the diameter of a circle.

Making D the subject of formula, we have:

D =\frac{circumference}{\pi}

Substituting the given parameters into the formula, we have;

D =\frac{15.4}{3.142}

D = 4.90 cm

To the nearest whole number:

D = 4.90 ≈ 5.0 cm
