Question

the diameter of the wheel of a bus is 91cm . How many km will it travels in 500 rotation of the wheel​

Answer 1

Answer:

Step-by-step explanation:

Hencert the diameter of wheels is 91cm so perameterms is pai× do

22/7 × 91

22× 13

286cm

= 1 revolution

Hence 1 revolution = 286 cm

Therefore 500 revolution = 286×500

=143,000cm

hence 1 km= 1000m and

1 m= 100cm

Therefore 100,000cm= 1km

So

143,000cm= 143,000/ 100,000=

1.43 km

Answer 2

Hi friends, here is your answer :-

Given diameter of wheel of a bus = 91cm

Now perimeter = 2πr

= 2×3.14×91/2 ( diameter= radius/2)

= 285.74 is the perimeter

now for 1 rotation it goes 285.74cm

for 500 rotations= 285.74×500

= 142870cm= 1428.7m (is your answer)

HOPE IT HELPED YOU..............
