Zeichne die figür in dein heft Berechne Umfang und Flacheninhalt der figur?

Answer 1

[merkurus]

a)
U = (2,5 * 2 * PI() / 2) + 5
U =12.854 cm
---
A = 2,5^2 * PI() / 2
A = 9,817 cm²

b)
U = (3 * 2 * PI() / 4) + (2 * 3)
U =10,712 cm
---
A = 3^2 * PI() / 4
A = 7,069 cm²

c)
U = (3 * 2 * PI() / 4 * 3) + (2 * 3)
U =20,137 cm
---
A = 3^2 * PI() / 4 * 3
A = 21,206 cm²

d)
U = (2,5 * 2 * PI() / 2) + 5 + (2 * 2)
U =16,854 cm
---
A = (2,5^2 * PI() / 2) + (5 * 2)
A = 19,817 cm²

e)
U = (1,5 * 2 * PI() / 2 * 2) + (2 * 5)
U = 19,425 cm
---
A = (1,5^2 * PI() / 2 * 2) + (5 * 3)
A = 22,069 cm²

f)
U = (1 * 2 * PI() / 2) + 6 + (4 * 2)
U = 17,142 cm
---
A = (1^2 * PI() / 2) + (6 * 2)
A =13,571 cm²
