Answer:
113.04 units^2
Step-by-step explanation:
The area of a circle can be found using:
[tex]a=\pi r^{2}[/tex]
First, we need to find the radius, since we have the diameter.
Radius
The radius is half the diameter, or
r=d/2
We know the diameter is 12, so we can substitute that in
r=12/2 Divide
r=6
Area
Now we know the radius and can substitute it into the area formula
[tex]a=\pi r^{2}[/tex]
[tex]a=\pi 6^2[/tex] Solve the exponent
[tex]a=\pi 36[/tex]
Substitute 3.14 in for pi
a=3.14*36 Multiply
a=113.04
We aren't given a specific unit, so we can say the area is
113.04 units^2
