Answer:

The correct options are Option A and Option D

Step-by-step explanation:

Mark wants to find the area of a circle with a diameter of 6 cm.

We need to find the expressions can he use to find the area of the circle in square centimetres?

The formula used to find area of circle is: [tex]Area=\pi \:r^2[/tex]

We are given Diameter = 6 cm

Radius = Diameter/2 = 6/2 = 3 cm

We get radius = 3cm

Now, putting values and finding area

[tex]Area=\pi \:r^2\\Area=\pi \:(3)^2\\Area=3^2\:\pi[/tex]

We can also write it as:

[tex]Area=3*3*\:\pi[/tex]

So, correct options are Option A and Option D
