Question

A bicycle wheel makes 500 revolutions in moving 1 km. Find the diameter

of the wheel.​

Answer 1

$\huge\frak\pink{Answer}$

A bicycle wheel makes 500 revolutions in moving 1 km.

In 1 revolution, the bicycle wheel covers

= 1/500 km = 1000/500 m = 2m

1 revolution distance = circumference of the wheel

⇒ 2πr = 2

⇒ 2×22/7×r =2

⇒ r= 2×7/22x2

= 7/22

Therefore, diameter (d) = 2r = 2×7/22 = 7/11 = 0.636 m.

Answer 2

$\huge\mathtt\pink{♡Answer♡}$

A bicycle wheel makes 500 revolutions in moving 1 km.

In 1 revolution, the bicycle wheel covers

= 1/500 km = 1000/500 m = 2m

1 revolution distance = circumference of the wheel

⇒ 2πr = 2

⇒ 2×22/7×r =2

⇒ r= 2×7/22x2

= 7/22

Therefore, diameter (d) = 2r = 2×7/22 = 7/11 = 0.636 m [Final ans].
