Question

Radius of a cycle wheel is 40 cm if the wheel rotates 100times in a minute find the distance covered by the cycle in 20 minutes

Answer 1

Answer: 502660 cm ( approx )

Step-by-step explanation: Circumference =2πr

r = 40 cm

2 x 22/7 x 40

1760/7

251.33cm ( approx )

Then for 100 rotations = 251.33 x 100

25133 cm

For 20 minutes = 25133 x 20

502660 cm ( approx )
