Question

The radius of circular wheel is 1.75 cm. How many revolutions will it make in travelling 11 km. (\pi = 22/7)

Answer 1

Answer:

1000

Step-by-step explanation:

Radius of circular wheel = 1.75 m  

Circumference of circular wheel =2Πr

⇒ 2 × 22/7 × 1.75m

∴ No. of revolutions = Distance to be covered ÷ Circumference of circle

$=\frac{11000m}{2*227*1.75m}$$=\frac{11000}{11} =1000$

Answer: The circular wheel will make 1000 revolutions in travelling 11 km.
