A button has a diameter of 0.80 inches what is the exact area of the button in terms of PI and then parentheses TT
The exact area of the button can be calculated using the formula for the area of a circle:
A = πr^2
Given that the diameter of the button is 0.80 inches, the radius (r) would be half of the diameter, which is 0.40 inches.
Substitute the radius value into the formula:
A = π(0.40)^2
A = 0.16π square inches
Therefore, the exact area of the button in terms of PI and the approximation of π as "TT" is:
A = 0.16π square inches
A = 0.16TT square inches.
