Question

if the diameter the open paint the diameter of the open paint can lid is 4.4 in what is its area in square inches

Answer 1

The diameter of the lid is d= 4.4 in.

The formula for the area of circular lid is,

`A=(\pi(d)^2)/(4)`

Substitute the values in the formula to obtain the area of lid.

`\begin{gathered} A=(\pi\cdot(4.4)^2)/(4) \\ =(3.14\cdot19.36)/(4) \\ =3.14\cdot4.84 \\ =15.1976 \\ \approx15.20 \end{gathered}`

Thus area of lid is 15.20 square inches.
