37 x 6 =222
aire partie rectangulaire = 222 m²
les 2 demi cercle forment un cercle entier = pi * R²
= 3.14 * 3² = 28.26 m²
aire totale = 222 + 28.26 = 250.26 m²
Bonjour,
1/2 cercle + 1/2 cercle = 1 cercle
aire du cercle:
pi r²
r = 3
3,14*3² => 28,26
aire rectangle :
37*6 => 222
total:
222 + 28,26
=> 250,26 (m²?)
