Hey!


The formula for finding area of a circle is: π · r²


The diameter is 4.1. The radius is half the diameter. Divide the diameter by 2 to find the radius.


4.1 ÷ 2 = 2.05


r = 2.05

2.05² = 2.05 × 2.05 = 4.2025


4.2025 × π = 4.2025π m²

Answer:

Option (b) is correct.

The area of circle is 4.025 π m².

Step-by-step explanation:

 Given : A circle with diameter 4.1 m

We have to find the area of circle in term of π.

Since, given circle has diameter 4.1 m

Area of circle is given as π r²

Radius is half of diameter so radius is  [tex]\frac{4.1}{2}=2.05[/tex] m

Substitute, r = 2.05 m , we have,

Area of circle = π (2.05)²

Simplify, we get,

Area of circle = 4.025 π m².

Thus, The area of circle is 4.025 π m².
