A button has a diameter of 0.80 𝑖𝑛𝑐ℎ𝑒𝑠.

Question

What is the exact area of the button in terms of pi (𝜋)?

 

A=πr2

Answer 1

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 = π(0.40)^2
A = π(0.16)
A = 0.16π square inches

Therefore, the exact area of the button in terms of pi is 0.16π square inches.
