Finding circumference using our known feet length

Today for math we were doing measurement to find the circumference of a circle out on the courts. I had already worked out how many of my feet length in a metre from last weeks lesson. 4 feet lengths of my feet make a metre. So I used my feet length to measure the diameter of circle. It was 12 feet lengths for me so it must have been 3 metres. I then multiplied 3 metres using pi(π = 3.14) using the formula Circumference = 3.14 x 3 metres = 9.42m. So the circumference of the circle is 9.42m.
