To find the area of the button, we need to first find the radius. The radius is half the diameter, so the radius is 0.80/2 = 0.40 inches.
Now, using the formula for the area of a circle A = Οr2, we can substitute the radius into the formula:
A = Ο(0.40)2
A = Ο(0.16)
A = 0.16Ο
Therefore, the exact area of the button in terms of pi is 0.16Ο in2.
