Question

Find the area of circle with a radius of 70m(take pie 22/7)
​

Answer 1

15400 m²

Explanation:

The formula to find the area of the circle is:

`\sf A=\pi r^2`

Given that,

r = 70 m

Let us find the area of the circle

`\sf A=\pi r^2\\\\\sf A=(22)/(7)*70*70\\\\\sf A =15400 \:m^2`

Answer 2

• 15400 m²

--------------------

Use area formula for circle:

• A = πr²

Substitute 22/7 for π and 70 for r:

• A = (22/7)*70²
• A = 15400

The area is 15400 m².
