bonjour
Périmètre = 12 x
p ( 3) = 3 * 12 = 36
aire = 7 x /2 = 3.5 x
a ( 3) = 3 * 3.5 = 10.5
q (x ) = 2 pi x = environ 18.8
b (x) = pi x²
b ( 3 ) = pi 9 = environ 28.3
r (x) = 2 ( 2 + 3 x + 2 ) = 4 + 6 x + 4 = 6 x + 8
r ( 3 ) = 18 + 8 = 26
C (x) = 2 ( 3 x + 2 ) = 6 x + 4
C ( 3) = 18 + 4 = 22
q ( 3) = 2 pi 3 =
