A button has a diameter of 0.80 πππβππ .
What is the exact area of the button in terms of pi (π)?
Β
A=Οr2
Given that the diameter of the button is 0.80 inches, we can calculate the radius (r) by dividing the diameter by 2:
r = 0.80 inches / 2 = 0.40 inches
Now, we can substitute the radius into the formula for the area of a circle:
A = Ο(0.40)^2
A = Ο(0.16)
A = 0.16Ο square inches
Therefore, the exact area of the button in terms of pi is 0.16Ο square inches.
