No, if the diameter of a circle is 1/2, then the radius (which is half of the diameter) would be 1/4.
The formula for the area of a circle is given by A = πr², where A is the area and r is the radius.
So, substituting the value of radius (1/4) into the formula, we have A = π(1/4)² = π(1/16) = π/16.
Therefore, the area of a circle with a diameter of 1/2 would be π/16, not π.
