A button has a diameter of 0.80 inches.What is the exact area of the button in terms of pi
The area of a circle is given by the formula A = πr^2, where r is the radius of the circle.
Since the diameter of the button is 0.80 inches, the radius is half of that, which is 0.40 inches.
So, the exact area of the button in terms of π is:
A = π(0.40)^2
A = π(0.16)
A = 0.16π
Therefore, the exact area of the button in terms of π is 0.16π square inches.
