Question

Find the area of the circle. Leave your answer in terms of pi diameter is 4.1 m

Answer 1

area= pir^2
r=d/2
4.1/2=2.05
pi(2.05)^2
final answer: 4.2pi

Answer 2

Area of the circle will be (4.20
`\pi`)

Explanation:

We have to find the area of the circle with diameter given is 4.10 m.

Since radius of a circle is represented by
`((diameter)/(2))`

Therefore, radius of the circle =
`((4.1)/(2))` = 2.05 m

Formula of the area of a circle is A =
`\pi r^(2)`

So area of the circle with radius 2.05 m will be

A =
`\pi (2.5)^(2)`

= 4.20
`\pi`

Area of the circle will be (4.20
`\pi`)
