A button has a diameter of 0.80 πππβππ .
What is the exact area of the button in terms of pi (π)?
A=Οr2
A. 0.16Ο in2
A. 0.16Ο in2
B. 0.40Ο in2
B. 0.40Ο in2
C. 0.64Ο in2
C. 0.64Ο in2
D. 0.80Ο in2
C. 0.64Ο in2
To find the area of the button, we need to use the formula A=Οr^2, where r is the radius of the button. Since the diameter is 0.80 inches, the radius is half of that, which is 0.40 inches.
Now, we plug in the radius into the formula: A = Ο(0.40)^2 = 0.64Ο in^2.
Therefore, the exact area of the button in terms of pi is 0.64Ο in^2.
