Find the distance covered in 10 rotations by the front wheel of the road roller whose

diameter is 4 m.

αnѕwєr :-- ⤵️⤵️

hєrє,

numвєr σf rσtαtíσnѕ = 10

díαmєtєr σf whєєl = 4m

ѕσ, díѕtαncє cσvєrєd ín σnє rσund = 2 π r

= 2 × π × 2

= 4π

nσw,

díѕtαncє cσvєrєd ín 10 rσundѕ = 10 × 4π

= 10 × 4 × 22/7

= 40 × 22/7

= 880 / 7

= 125.71
