Question

The radius ofa wheel is 30cm .how much distance will it travel in 100revolution​

Answer 1

Answer:

Step-by-step explanation:

Circumference formula is 2πr.

Therefore ... 2 x 22/7 x 30cm =

188.5 this is the distance it will cover in one revolution ......in 100 revolution... it will cover 100 x 188.5 which 1885 cm .

Answer 2

Given,

Radius of wheel = 30 cm

Number of revolutions = 100

--------------------------------------------------------------

Now,

we know that...

Circumference of circle =

$2\pi r$

where pie = 22/7

so, circumference of wheel = 2 × 22/7 × 30

= 44/7 × 30

= 188. 57 cm

Distance travelled = Circumference

So distance travelled in 100 revolutions = 188.57 × 100

= 18857 cm

Answer = 18857 cm
