Answer 1

■ Oie td bom☺?!

• a) C = 2.π.r

• C = 2.3,14.3

• C = 6,28.3

• C = 18,84 m

• b) C = 6,28.7

• C = 43,96 m

• c) C = 6,28.23

• C = 144,44 m

• d) C = 6,28.50

• C = 314 m

• e) C = 6,28.8

• C = 50,24 cm

• d) C = 6,28.10

• C = 62,8 cm

• e) C = 6,28.5

• C = 31,4 cm

Answer 2

Oie, Td Bom?!

• Fórmula:

C = 2 . π . r

• π = 3,14

a) C = 2 . 3,14 . 3

C = 6,28 . 3

C = 18,84m

b) C = 2 . 3,14 . 7

C = 6,28 . 7

C = 43,96m

c) C = 2 . 3,14 . 23

C = 6,28 . 23

C = 144,44m

d) C = 2 . 3,14 . 50

C = 6,28 . 50

C = 314m

e) C = 2 . 3,14 . 8

C = 6,28 . 8

C = 50,24cm

d) C = 2 . 3,14 . 10

C = 6,28 . 10

C = 62,8cm

e) C = 2 . 3,14 . 5

C = 6,28 . 5

C = 31,4cm
