How do you calculate the circumference with the diameter?

For any circle, if you divide the circumference (u) by the diameter (d), you always get the number π. From this you get the circumference formula for the circle. Hint: If you don’t have a calculator with a π key, calculate with π≈3.14.

How do you calculate the perimeter and area of ​​a rectangle?

To calculate the perimeter u of a rectangle, add the lengths of the four sides: u = a + b + a + b = 2 a + 2 b = 2 ( a + b ) u=a+b+a+b=2a+ 2b=2(a+b) u=a+b+a+b=2a+2b=2(a+b). A special case of the rectangle is the square.
