The center circle of a football field is 2.1 metres across find the perimeter of the circle take π = 3.14

Answer 1

The formula to find the perimeter or circumference (C) of a circle is given by:
C = 2πr, where r is the radius of the circle.

We know the diameter (d) of the center circle is 2.1 meters, and we can find the radius (r) by dividing the diameter by 2:
r = d/2 = 2.1/2 = 1.05 meters.

Now, using the value of π = 3.14 and the radius (r = 1.05 meters) in the formula, we can calculate the perimeter (C) of the circle:
C = 2πr = 2 * 3.14 * 1.05 = 6.588 meters (rounded to three decimal places).

Therefore, the perimeter of the center circle is approximately 6.588 meters.
