THE DIAMETER OF A WHEEL OF A CAR IS 70CM. FIND THE DISTANCE COVERED BY THE CAR DURING THE TIME IN WHICH THE WHEEL MAKES 1000 REVOLUTIONS.
Answers
Answer:
r = 70/2 = 35cm
circumference = 2πr
= 2× 22/7×35
= 2×22×5
= 220cm
distance covered after 1000 revolutions
= 1000×220
= 220000cm
= 2200m
= 2.2km

Answer:
To find the distance first we have to find the how much distance the wheel will cover in one round that is circumference then by multoplying the circumference with 1000 we could find the distance.
Given
Diameter = 70 cm
Revolutions= 1000
Radius = d/2 = 70/2 = 35
Circumference = 2 × 22/7 × 35
= 44×5
= 220
So, distance = 220× 1000
= 220000cm
= 2200m
= 2.2 km
