Find the area of a circle whose radius is 7 meters.

Knowing the radius of a circle, you can always find the area of a given circle. The area of a circle is equal to the product of the square of the radius and pi.

Find the area of a circle with a radius of 7 m.

S = 7 ^ 2 * n (m ^ 2) = 49n (m ^ 2).

If you accept? that n ≈ 3.14, then

S ≈ 49 * 3.14 (m ^ 2) ≈ 153.86 m ^ 2.

Answer: the area of the circle is 49n m ^ 2.
