Answer 2

Answer:

12.57

Step-by-step explanation:

The formula to find the area of a circle is A=πr^2.  Radius is half the diameter, so the radius is 2.  2 squared is 4.  Now the equation is A=4π.  π, (pi,) should be used as 3.14 in this equation since your answer has to be a decimal.  3.14 multiplied by 4 = 12.57.
