(3 points)
О А. 0.16 in'
O B. 0.40 in?
OC. 0.64Tin
O D. 0.80 in?
C. 0.64 in^2
To calculate the area of the button, we use the formula for the area of a circle:
Area = π * (radius)^2
Given that the diameter of the button is 0.80 inches, the radius is half of the diameter:
Radius = 0.80 / 2 = 0.40 inches
Now, substitute the radius into the formula:
Area = π * (0.40)^2
Area = 0.64π in^2
Therefore, the exact area of the button in terms of pi is 0.64π square inches.
