Question

The diameter of A wheel of a circle is 70 cm how many revolutions will it make to travel one kilometre

Answer 1

Answer:

454$\frac{6}{11}$ revolutions

Step-by-step explanation:

d = 70cm

⇒ r = 35cm

⇒circumference = 2pi×r

= 2×22×35/7

=220 cm

1km= 100000cm

no of revolutions = 100000/220

= 454$\frac{6}{11}$

Answer 2

Answer:

454 6/11is the correct answer
