To find the area of the button, we first need to calculate the radius of the button. The diameter is given as 0.80 inches, so the radius would be half of that, which is 0.40 inches.

Now, we can use the formula for the area of a circle: A = Ο€r^2
Substitute the radius into the formula: A = Ο€(0.40)^2
A = Ο€(0.16)
A = 0.64Ο€ in2

Therefore, the exact area of the button in terms of pi is 0.64Ο€ in2.
