What’s the area of a circle with a diameter of 4
umka21 [38]

Answer:

4\pi ≈ 12.57 units squared

Step-by-step explanation:

The area of a circle is denoted by: A=\pi r^{2}, 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: A=\pi *2^2=4\pi

We can round 4pi to 12.57 units squared.

Hope this helps!
