Question

The number of revolutions a wheel of diameter 40 cm makes in travelling a distance of 176 m is equal to.....
pls show the process..​

Answer 1

Answer:

141

The number of revolutions a wheel of diameter 40 cm makes in travelling a distance of 176 m is 141 . Hence the number of revolutions a wheel of diameter 40 cm makes in travelling a distance of 176 m is 141 .

plz mark brainliest..,..!

Answer 2

Answer:

diameter =40cm

radius=20cm

therefore,

circumference=2πr

=2×22/7×20=880/7

distance travelled = 176m=17600cm

therefore no. of revolutions made = (17600/880)×7

=140 revolutions (ans)

hope u like it :)

mark me as the brainliest if u r satisfied with the answer.
