Question

the diameter of a wheel of a car is 42 cm. find the distance travelled by the car during the period in which the wheel makes 500 revolutions
$2\pi = 22\7$
​

Answer 1

Step-by-step explanation:

Diameter of wheel is 42cm

Radius = 21cm

Circumference = 1 revolution of wheel

Therefore for 500

= 500 * circumference of wheel

$500 \times \frac{2 \times 22 \times 21}{3}$

= 66,000cm

Answer 2

Step-by-step explanation:

Diameter of wheek =42

radius = 21

circumference = 1 revolution of wheels

therefore 500

500 × circumference of wheel

500

$\frac{2 \times 21 \times 21}{3}$

=66000
