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,
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,


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


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

Answer:
490 pi units^3
Step-by-step explanation:
The volume of a cylinder is given by
V = pi r^2 h
The diameter is 14 so the radius is 14/2 = 7
V = pi (7)^2 * 10
V =490 pi
