A potter’s wheel of diameter 1.4 meter revolves 5 times in 1 minute.

1.	A potter’s wheel of diameter 1.4 meter revolves 5 times in 1 minute. Find the distance covered by the wheel in 6 second?1. 4.42. 2.23. 3.34. 5.5
Answer» Correct Answer - Option 2 : 2.2 Given: Diameter of wheel = 1.4 m Radius of wheel = 1.4/2 = 0.7 m No. of revolution in 60 second = 5 Concept: Calculate the no. of revolution of the wheel in 6 second, and then multiply it with the circumference of the wheel. Formula Used: Circumference of circle = 2πr Where, r → Radius of circle Calculation: Number of revolutions in a second = 5/60 = 1/12 No of revolution in 6 second = 6/12 = 1/2 Distance covered by the wheel in 6 seconds = (1/2) × 2 × (22/7) × 0.7 = 2.2 m ∴ Distance covered by the wheel in 6 seconds = 2.2 m

Answer» Correct Answer - Option 2 : 2.2

Given:

Diameter of wheel = 1.4 m

Radius of wheel = 1.4/2 = 0.7 m

No. of revolution in 60 second = 5

Concept:

Calculate the no. of revolution of the wheel in 6 second, and then multiply it with the circumference of the wheel.

Formula Used:

Circumference of circle = 2πr

Where,

r → Radius of circle

Calculation:

Number of revolutions in a second = 5/60 = 1/12

No of revolution in 6 second = 6/12 = 1/2

Distance covered by the wheel in 6 seconds = (1/2) × 2 × (22/7) × 0.7 = 2.2 m

∴ Distance covered by the wheel in 6 seconds = 2.2 m
