Answer: 50.24 square centimeters.

Explanation:

Given: The radius of the circular lens of a magnifying glass = 4 centimeters

The area of a circle is given by :-

$\text{Area}=\pi r^2$ , where r is the radius of the circle.

Then the area of the circular lens of a magnifying glass is given by :-

$\text{Area}=\pi (4)^2=(3.14)(16)=50.24\text{ square centimeters }$

Hence, the area of the circular lens of a magnifying glass = 50.24 square centimeters.
