Question

Eighth gradeT.5 Area and circumference of circles CHVThe diameter of a circle is 8 feet. What is the circle's circumference?d=8 ftUse 3.14 for .

Answer 1

The circumference of a circle can be calculated using the following formula:

$C=\pi d$

Where "C" is the circumference of the circle and "d" is the diameter of the circle.

According to the information given in the exercise, the diameter of this circle is:

$d=8ft$

Knowing the diameter, you only need to substitute it into the equation. Remember that you need to use

$\pi=3.14$

Then:

$\begin{gathered} C=(3.14)(8ft) \\ C=25.12ft \end{gathered}$

The answer is:

$25.12ft$
