1.	A bicycle wheel makes 5000 revolutions in moving 11 km. Find the diameter of the wheel.
Answer» Given total distance covered by bicycle in 5000 revolutions = 11 km = 11000 m Therefore distance covered in 1 revolution = 11000/5000 = 2.2 m = 11/5 Distance covered in 1 revolution = Circumference of the wheel C = πd 11/5 = (22/7) d d = (11 × 7)/ (5 × 22) d = 77/110 d = 0.7 m Therefore diameter of wheel = 0.7 m = 70 cm

A bicycle wheel makes 5000 revolutions in moving 11 km. Find the diameter of the wheel.

Answer»

Given total distance covered by bicycle in 5000 revolutions = 11 km = 11000 m

Therefore distance covered in 1 revolution = 11000/5000 = 2.2 m = 11/5

Distance covered in 1 revolution = Circumference of the wheel

C = πd

11/5 = (22/7) d

d = (11 × 7)/ (5 × 22)

d = 77/110

d = 0.7 m

Therefore diameter of wheel = 0.7 m = 70 cm
