Answer: A=28.26 units²
Explanation:
The formula for the area of a circle is A=πr²
You find the radius of the circle by dividing 6 by 2
because diameter is twice the radius.
Then you plug in 3 as radius to the equation.
So the equation looks like this:
A=3.14×3²
Then solve the equation:
A=3.14×9
A=28.26 units²
