The circumference of the pad to the nearest tenth is 39.6 meters

Formula for calculating the circumference of a circle?

The circumference of a circle is the arc length of the circle, as if it were opened up and straightened out to a line segment. It is also known as the perimeter of a circle.

The formula for calculating the circumference of a circle is expressed as;

C = 2πr

where

π = 3.14

r is the radius of the circle

Given the following parameters

π = 3.14

r = 6.3m

Substitute to have:

C = 2 * 3.14 * 6.3

C = 6.28 * 6.3

C = 39.564

Hence the circumference of the pad to the nearest tenth is 39.6 meters
