Answer:
28.26
Step-by-step explanation:
A = pi radius squared
A = 3.14 x 9
A= 28.26
Answer: A=28.26 units²
Step-by-step explanation:
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
