The circumference of a circle is 7π m. What is the area of the circle? 3. 5π m² 12. 25π m² 14π m² 49π m².

Area of the circle is the area covered by that circle. The area of the circle whose circumference is 7π m is 12.25π m².

<h3>What is the area of a circle?</h3>

The area of the circle is the area covered by that circle. It is given by the formula,

$\text{Area of the circle}=\pi r^2$

where r is the radius of the circle.

As it is given that the circumference of a circle is 7π m. Therefore, the radius of the circle can be written as,

$\text{Circumference of the circle} = 2\pi r$

$7 \pi = 2 \pi r\\\\r = 3.5\rm\ m$

Now, we know the formula of the area of a circle, therefore, the area of the circle can be written as,

$\text{Area of the circle}=\pi r^2$

$= \pi \times (3.5)^2\\\\= 12.25\pi\rm \ m$

Hence, the area of the circle whose circumference is 7π m is 12.25π m².
