Question

When a car moves forward by 180cm, each wheel does one full turn.

what is the diameter of the wheels to the nearest centimetre?
PLS EXPLAIN THE SIMPLEST WAY YOU CAN OF HOW YOU DID THIS QUESTION THANKS SO MUCH

Answer 1

If the wheel does one full turn in 180 cm, that means the wheels circumference is 180. The equation for circumference is:
Circumference = (Pi) x Diameter
(Can't find the symbol for pi)

Now plug in the 180 for the Circumference:
180 = (Pi) x D

Divide by Pi:
57.296 = D

ANSWER:
The diameter is 57 cm
