C. 0.64ฯ in2
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 = ฯr2, we can substitute the radius into the formula:
A = ฯ(0.40)2
A = ฯ(0.16)
A = 0.16ฯ
Therefore, the exact area of the button in terms of pi is 0.16ฯ in2.
A button has a diameter of 0.80 ๐๐๐โ๐๐ .
What is the exact area of the button in terms of pi (๐)?
