the diameter of a wheel is 84cm? How far it travels in one turn?

C = pi * d

C = 3.14 * 84
C = ?

263.76 To determine how far a wheel travels in one turn, you can use the formula for the circumference of a circle, which is given by:

Circumference = π * Diameter

In this case, the diameter of the wheel is given as 84 cm. To find the circumference, substitute this value into the formula:

Circumference = π * 84 cm

Now, we need to know the value of π. Pi (π) is a mathematical constant that represents the ratio of a circle's circumference to its diameter, which is approximately 3.14159.

Therefore, the equation becomes:

Circumference = 3.14159 * 84 cm

Simplifying the equation, we have:

Circumference = 263.89376 cm

So, the wheel travels approximately 263.89376 cm in one turn.
