Answer:
[tex]4\pi[/tex] ≈ 12.57 units squared
Step-by-step explanation:
The area of a circle is denoted by: [tex]A=\pi r^{2}[/tex], where r is the radius.
Remember that diameter is twice the radius, so since the diameter equals 4, we know that the radius r = 4/2 = 2.
Now, plug this in: [tex]A=\pi *2^2=4\pi[/tex]
We can round 4pi to 12.57 units squared.
Hope this helps!
