Question

Calcule a área da região colorida de cada figura, considerando PI = 3,14 e Raiz de 3 = 1,73

Answer 1

a1= π6^2/2 =18π= 18.3,14=56,52cm2

a2=6.12= 72cm²

A=72-56,52=15,48cm²

b)
a1=6.6√3/2 = 36√3/2 = 18.1,73=31,14

a2=3(π3².60/360) = 3(9π/6) = 3(1,5π )=3.4,71=14,13

A=a1-a2
A=31,14-14,13=17,01cm²
