Resposta:

1) 6,369cm

2) 31,40cm

3) 62,8cm

4) 12.560cm ou 12,56m

5) 314cm

Explicação passo a passo:

1)

C = 2.π.r

40 = 2.3,14.r

40 = 6,28r

40/6,28 = r

6,369cm = r

2)

C = 2.π.r

C = 2.3,14.5

C = 6,28.5

C = 31,40cm

3)

C = 2.π.r

C = 6,28.10

C = 62,8cm

4)

C = 2.π.r

C = 6,28.2000

C = 12.560cm ou 12,56m

5)

C = 2.π.r

C = 6,28.50

C = 314cm
