Answer:
[tex]A=4.2025\pi[/tex]
Step-by-step explanation:
A circle is a curve made up of all the points having the same distance from the center. In terms of the diameter, that is any chord that passes through the center, the area can be found as:
[tex]A=\pi (\frac{d}{2})^2[/tex]
We know that [tex]d=4.1m[/tex] then:
[tex]A=\pi (\frac{4.1}{2})^2 \\ \\ A=\pi (2.05)^2 \\ \\ A=4.2025\pi[/tex]
So [tex]4.2025\pi[/tex] is the result and as you can realize this area is in terms of π
