Question

A scooter wheel makes 50 revolutions to cover a distance of 8800 cm . Find the radius of the wheel .

Answer 1

heya;

first we will divide 8800 by 50
so that gives us 176

therefore 176 is the circumference of the circle

circumference=2πr
176=2×22\7×r
176×7=44r
1232\44=r
r=28

thank you
hope it helps:)

Answer 2

Hey friend here is your answer......


Solution :


Distance travelled = Number of revolutions X circumference


$circumference = \frac{distance \: travelled}{number \: of \: revolutions}$

$2\pi r = \frac{8800}{50}$

$i.e \: 2\pi \:r = 176$

$2 \times \frac{22}{7} \times r = 176$

$r = \frac{176 \times 7}{2 \times 22}$

$r = 28 \: cm$


Therefore radius of the wheel = 28cm.


Hope it helps you......
