Question

Find he area of the circle. Leave your answer in terms of pie.

Answer 1

Option (b) is correct.

The area of circle is 4.025 π m².

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
`(4.1)/(2)=2.05` 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.

Answer 2

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
