Question

How many times a wheel of radius 28cm must rotate to go 352 m?

Answer 1

HEY MATE HERE IS YOUR ANSWER.....

RADIUS OF WHEEL(circle):28cm.
CIRCUMFERENCE OF WHEEL(circle):2πr.

$= > 2 \times \frac{22}{7} \times 28 \\ = > 2 \times 22 \times 4 \\ = > 44 \times 4 \\ = > 176cm$
$no. \: of \: revolution = \frac{total \: revolutions(distance)}{circumference} \\ = > \frac{352}{176} \\ = > 2 revolution$
