We know that the diameter of a circle is 2 times the radius.
If the radius is 0.75 meters, then the diameter must be 2 x 0.75 meters = 1.5meters
The equation is simply 8s where s is the length of a side. There are 8 sides. You are just adding the length of all 8 sides together to get the perimeter.
