Given:

The diameter of the circle is 6.6m.

To find:

The area and the circumference of the circle.

Step-by-step explanation:

The radius of the circle is,

$\begin{gathered} r=(d)/(2) \\ r=(6.6)/(2) \\ r=3.3m \end{gathered}$

Using the formula of the area of the circle is,

$\begin{gathered} A=\pi r^2 \\ A=\pi(3.3)^2 \\ A=10.89\pi m^2 \end{gathered}$

Using the formula for the circumference of the circle is,

$\begin{gathered} C=2\pi r \\ C=2\pi(3.3) \\ C=6.6\pi m \end{gathered}$

Final answer:

The formula of the area of the circle is,

$A=10.89\pi m^2$

The formula for the circumference of the circle is,

$C=6.6\pi m$
