Answer 1

Question ↘️

How many times a wheel of radius 28 cm must rotate to go 176 m ?

[π = 22/7 ]

Answer ↘️

Radius - 28 cm

CIRCUMFERENCE - 2πr

$2 \times \frac{22}{7} \times 0.28m$

because - 1 cm = 0.01 m

2 × 22 × 0.04

1.76 m

Now total distance - 176 m

in one round - 1.76 m

so,

$\frac{176}{1.76}$

=> 100

Thus,

Wheel have to take 100 rounds to cover distance of 176 m
