Question

The diameter of a circle is 6 centimeters. What is the area?give the exact answer in simplest form.

Answer 1

The diameter of the circle is 6cm

The area of a circle is given as

`A=\pi r^2`

The radius of the circle is

`r=(6)/(2)=3`

Therefore, the area of the circle is

`A=\pi*3^2^{}`

This gives

`\begin{gathered} A-9\pi \\ A=28.3 \end{gathered}`

Therefore, the area of the circle is 28.3 cm²
