Respuesta:
a) A = 28,26 mm²
b) A = 9,6m²
c) A = 12,56m²
Explicación paso a paso:
A = π x r²
a) datos
r = 3 mm
π = 3,14
A = 3,14 x (3 mm)²
A = 3,14 x 9 mm²
A = 28,26 mm²
b) datos
r = 3,5m/2 = 1,75m
A = 3,14 x (1,75 m)²
A = 3,14 x 3,06 m²
A = 9,6m²
c) datos
r = 2m
A = 3,14 x (2m)²
A = 3,14 x 4m²
A = 12,56m²
