Question

The diameter of a circle is 40 m find the area of the circle in term of pie?
40

Answer 1

Pi × radius^2. Radius=20 m Pi × 20^2 Area= 400pi m^2

Answer 2

Answer: The required area of the given circle is
`400\pi~\textup{m^2}.`

Step-by-step explanation: We are given that the diameter of a circle i 40 m.

We are to find the area of the circle in terms of pie.

We know that

the AREA of a circle with radius of length r units is given by

`A=\p r^2.`

Since the diameter of the given circle is 40 m, so the length of the radius is given by

`r=(40)/(2)=20~\textup{m}.`

Therefore, the AREA of the circle is given by

`A=\pi r^2=\pi* 20^2=400\pi~\textup{m}^2.`

Thus, the required area of the given circle is
`400\pi~\textup{m}^2.`
