What’s the area of a circle with a diameter of 4

≈ 12.57 units squared

Step-by-step explanation:

The area of a circle is denoted by: , 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:

We can round 4pi to 12.57 units squared.

Hope this helps!

12.56 units²

Step-by-step explanation:

Radius = 4/2 = 2

Area = pi × r²

3.14 × 2²
