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

1 answer

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.
