answer:
The area of a circular horse pen can be calculated using the formula A = πr^2, where A is the area and r is the radius of the pen.
Given that the diameter of the pen is 12 meters, we can find the radius by dividing the diameter by 2:
Radius (r) = Diameter / 2 = 12 / 2 = 6 meters
Substituting the radius into the formula, we get:
A = 3.14 * (6)^2 = 3.14 * 36 = 113.04 square meters
Rounding to the nearest 100th, the area of the horse pen is approximately 113.04 square meters.
