Question

If the radius of a bicycle wheel was 14cm how far will it travel in five complete turns

Answer 1

Answer:

Radius of the bicycle wheel (which is a circle): 14 cm

We know,

Circumference of a circle: 2πr

Area of a circle: πr²

When a bicycle wheel moves, the circumference is the distance travelled by the times the wheel moved.

In the given question, the wheel moves 5 complete turns.

So, the distance travelled by the bicycle will be: 2πr×5

➜ 10πr

➜ 10×22/7×14

➜ 10×22×2

➜ 44×10

➜ 440 cm

Hence, the total distance travelled is 440 cm.
