How do you work out the perimiter of a circle?
The perimeter of a circle is called it circumference, "C". To calculate it, multiply its diameter by the constant, pi. Pi is roughly equal to 3.14159265. So, let's say you have a circle with a 10-foot diameter. Then C=10 x 3.14159265 = 31.42 (rounded off).

How do you calculate the stirrups cutting length?
Firstly, u need 2 know ur diameter of the stirrup used. Then get the perimeter of ur concrete work. After which you will less your cover, but remmeber that your diameter stirrup will be minus from your cover in meter, then u can now less cover round the perimeter of your concrete and lastly you will add your bending length(i.e the length it use to over_laps each other. Which is mostly 75mm.
