To calculate the perimeter of a square, which formula(s) can be used?

P = s^2

P = 4 • s

P = s + s + s

P = s + s + s + s
The formula for the circumference of a circle is:

C = πr^2

C = π • d

C= 2L + 2W

C = 2 • r
The radius is half the diameter.
True

 True<----my answer
 False

hartnn · Answer

square has all 4 sides equal
so Perimiter of square will be 4 times its side

hartnn · Answer

Circumference of circle formula :$C =2\pi r $

hartnn · Answer

radius is indeed half the diameter :)
true is correct :)

anonymous · Answer

yup wat @hartnn said was right @kittymeow101

hartnn · Answer

and 2r = d
so 
$C =\pi d$

ok ty!
