Question

5. Find the distance covered by the wheel of a car m 500 revolutions if the diameter of the wheel is 77 cm.​

Answer 1

Answer:

THE DISTANCE COVERED BY THE WHEEL= 121000

Step-by-step explanation:

Circumference of circle = 2πr

Radius of Circle = (77/2)

Now, Putting the Values,

2×22/7×77/2 = 242

That means 1 revolution = 242

then, 500 revolution = 242×500

= 121000

SO THE DISTANCE COVERED BY THE WHEEL= 121000

Answer 2

$\sf Circumference \: of \: circle = 2πr$

$\sf Radius \: of \: Circle = (77/2)$

$\sf Now, Putting \: the \: Values$

$\frac{2 \times 22}{7 \times 77} \times 2$

$\sf That \: means \: 1 \: revolution = 242$

$\sf then, 500 revolution \\ = 242 \times 500 \\ = 121000$

$\sf ∴SO \: THE \: DISTANCE \: COVERED \: BY \: THE \: WHEEL= 121000$
