    Answer:

    Hello! answer: 12.56

    Step-by-step explanation:

    Area for circles is found be doing

    radius × radius × pi since we arent given radius we have to figure it out. But what we do know it diameter is just 2 times the radius so to undo that to find our radius we just do 4 ÷ 2 and 4 ÷ 2 = 2 so 2 is our radius now we will square it which is just fancy for multiply is by itself so 2 × 2 = 4

    4 × 3.14 = 12.56 So 12.56 is our area! Hope this helps you!
