# How many times a wheel of radius 28 cm must rotate to go 352 m? (Take π = 22/7)

**Solution:**

Radius of wheel = 28 cm

Circumference of wheel = 2πr

= 2 × 22/7 × 28 cm

= 2 × 22 × 4 cm

= 176 cm

Total distance = 352 m = 35200 cm

Number of times the wheel should rotate = Total distance covered by wheel / Circumference of the wheel

= 35200/176

= 200

**Video Solution:**
