Question

The diameter of your bicycle wheel is 25 inches. How far will you move in two turns of your wheel? Use 3 for π.

Answer 1

In 1 turn, you will move = πD = 3.14 * 25 = 78.5 inches

In 2 turns, you will move = 78.5 * 2 = 157 inches

Answer 2

Answer: The answer is 157 inches.

Step-by-step explanation: Given that the diameter of the wheel is 25 inches. We are to find the distance we will move in two turns.

The distance moved in one turn is equal to the circumference of the wheel.

We know that if 'd' is the diameter of a circle, then its circumference will be

`C=\pi d.`

Given that

`\pi=3.14.`

So, the circumference of the wheel is

`C_w=\pi * 25=3.14* 25=78.5~\textup{inches}.`

Therefore, distance moved in 1 turn = 78.5 inches.

Hence. distance moved in two turns = 2 × 78.5 = 157 inches.

Thus, the answer is 157 inches.
