Question

The diameter of a cycle wheel is 70 cm. Find how many times the wheel will rotate in order to cover a distance of 110 m. Find the answer?

Answer 1

Answer:

Hi friend here is the answer ✨

Let the radius of the wheel be r

Then,

$r = \frac{70}{2} \: cm \: = 35 \\\: cm \\ \\ circumference \: of \: the \: wheel \: = 2\pi \\ = 2 \times \frac{22}{7} \times 35cm \\ = 220cm = \frac{220}{100} \\ = 2.2cm \\ number \: of \: revolutions = \frac{distance}{circumference} \\ = \frac{110 \: m}{2.2 \: m} \\ = 50$

✅ HENCE,THE CYCLE WHEEL WILL ROTATE 50 TIMES TO COVER A DISTANCE OF 110 m
