Question

the wheel of a car rotated 1000 times in travelling a distance of 1.76km.find the radius of the wheel.(take pie=22/7)​

Answer 1

Answer:

If the wheel of a car rotated 1000 times in travelling a distance of 1.76km, then the radius of the wheel is 0.28m.

Step-by-step explanation:

Given: Total distance = 1.76km

Number of rotation of the wheel of car = 1000 times

Find the radius of the wheel.

Let the radius of wheel = r

The wheel moves 2πr distance in one rotation

for 1000 times (rotations)

it moves 1000 (2πr)

Given that is equal to 1.76 km = 1760 km

1000(2πr)=1760

2000× 22/7×r=1760

r= 56/200

r= 7/25 m = 0.28 m

∴ radius of wheel = 0.28 m
