The diameter of a wheel is 1.33 m. What distance (in m, to the nearest whole number) will it 380 revolutions?

(Takeπ=227)(Take\pi={{22} \over 7})

 

Show answer & explanation

Correct answer: D

Explanation

The correct answer is Option 4 i.e. 1588.

Given:

Diameter = 1.33m

Revolutions = 380

Concept Used:

Distance = Number of revolutions × circumference of wheel

Explanation:

According to the given question,

Circumference of wheel = 2πr2 \pi r = 2×227×1.3322 \times { 22\over 7} \times {1.33 \over 2} = 4.18 m

Now, distance = 380 × 4.18 = 1588

Hence the required answer is 1588 m.
