Answer:
4[tex]\pi[/tex] or 12.57
Step-by-step explanation:
First, write down the formula for the area of a circle
A= [tex]\pi r^{2}[/tex]
Then, write down your known values
r = 2
Now, substitute the value r for 2
A = [tex]\pi (2)^{2}[/tex]
Then, find the value for [tex](2)^{2}[/tex]
A = [tex]\pi[/tex](4)
Next, multiply [tex]\pi[/tex] and 4
A = 4[tex]\pi[/tex]
Your answer would be 4[tex]\pi[/tex] or 12.57, which ever way you need it.
