Saira is using the formula for the area of a circle to determine the value of LaTeX: \piπ. She is using the expression LaTeX: Ar^{-2}\:A r − 2where LaTeX: A\:=\:50.265\:A = 50.265and LaTeX: r\:=\:4\:r = 4. Use a calculator to evaluate Saira's expression to find her approximation for the value of LaTeX: \pi\:πto the nearest thousandth.

Given:

Area of a circle, A=50.265 sq. units.

Radius of circle, r = 4 units.

To find:

The value of π to the nearest thousandth.

Solution:

Formula for area of a circle is

Now, using expression, we can find the value of π.

Approximate the value to the nearest thousandth (three digits after decimal).

Therefore, the approximated value of π is 3.142.
