Question

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

Answer 1

3.164

Explanation:

Given the area if the circle used by Sarah expressed as

A = πr²

Given

A = 50.265

r = 4

To get π, we will substitute the given values into the formula as shown

50.625 = π{4)²

50.625 = 16π

π = 50.625/16

π = 3.164

Hence her approximate value to nearest thousandth is 3.164
