The circumference (C) of a circle can be calculated using the following formula: C = pi *d
Since the diameter (d) is equal to 2 times the radius (r), we can write: C = pi * 2 * r
Let's round pi to 3.14 and determine the radius:
C= 3.14 * 2 r
266.9 = 3.14 * 2 * r
266.9 = 6.28 * r
266.9/6.28 = r
42.5 meters = r
Then to find how long it would take to walk around the circular garden one time at 50 meters per minute, you would divide the circumference by 50. NOTE: The circumference is the actual distance you would walk.
266.9 / 50 = 5.34 minutes to walk around 1 time
To walk around the garden twice would be: 2 * 5.34 = 10.68 minutes
