Question

if radius of a wheel of a car is 2cm. then to cover a distance of 1000m. how many revolutions will it take?​

Answer 1

Answer:

because it is having two brothers

Answer 2

Answer:

Radius = 2 cm

Then, circumference = 2πr

=

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

$\frac{22}{7} \times 4$

=

$\frac{88}{7}$

Since, distance = 1000 m

Therefore, No. of revolutions =

$\frac{distance}{circumference}$

=

$1000 \div \frac{88}{7}$

=

$1000 \times \frac{7}{88}$

$\frac{1000 \times 7}{88}$

= 79.54 or 80 revolutions, when rounded off.
