Answer:

The answer is A) 12.56 square inches

Step-by-step explanation:

The equation to find the answer is 3.14×r²

r standing for radius. To find the diameter, you simply multiply the radius by 2.

Because they already gave us the diameter, the equation to solve this question is 3.14×4

3.14×4=12.56
