Question

how many times will the wheel of a car rotate in a journey of 88km, given that the diameter of the wheel is 56cm​

Answer 1

Step-by-step explanation:

Diameter of wheel = 56 cm

Radius of wheel = \frac{56}{2}=28 cm

2

56

=28cm

Circumference of wheel = 2 \pi r = 2 \times \frac{22}{7} \times 28 = 176 cm2πr=2×

7

22

× 28=176cm

So. No. of revolutions in 176 cm (0.00176)= 1

No. of revolutions in 88 km = \frac{88}{0.00176}=50000

0.00176

88

=50000
