Answer 1

Step-by-step explanation:

Distance travelled by wheel in nth Revolution is = n × Circumference of circle.

Circumference of circle having radius 42 is = 2π× 42

1)

Distance travelled in 1 revolution = 1 × 2π × 42 = 263.76cm

2)

Distance travelled in 50 revolution = 50 × 2π × 42 = 13188cm

3)

Distance travelled in 200 revolution =

200 × 2π × 42 = 52752cm

Answer 2

Answer:

Step-by-step explanation:
