The radius of a circular field is 31.5 meters.what is its circumference ?
C = pi * d
C = 3.14 * 63
C = ?
To find the circumference of a circle, we can use the formula:
Circumference = 2 * π * Radius
First, let's substitute the given radius into the formula:
Circumference = 2 * π * 31.5 meters
Now, let's calculate the circumference using the value of π. The value of π is approximately 3.14159 (commonly rounded to 3.14):
Circumference = 2 * 3.14 * 31.5 meters
Performing the calculation:
Circumference = 6.28 * 31.5 meters
Multiplying these numbers gives us:
Circumference = 197.82 meters
Therefore, the circumference of the circular field is 197.82 meters.
