Find the area of a circle if its radius is 8 m.

In order to find the area of a circle, if the length is known, its radius is 8 meters, recall and apply the formula for finding the area of a circle.

There are two formulas for finding the area of a circle:

1. Formula for finding the area of a circle through the diameter:

S = 1 / 4nd ^ 2, where d is the diameter of the circle, and the number n = 3.14.

2. Formula for finding the area of a circle in terms of the radius:

S = 2пR ^ 2, where R is the radius of the circle.

Since we are given a radius, we will use the second formula:

S = 2 * 3.14 * 8 ^ 2 = 6.28 * 64 = 401.92 square meters area of the circle.
