Answer 2

Step-by-step explanation:

FIRST WE NEED TO ANALYSE GIVEN DATA

DIAMETER=14m

THEN,

RADIUS=d/2=14/2=7m

WE NEED TO FIND CIRCUMFERENCE OF THE CIRCLE

CIRCUMFERANCE= 2πr

=2×7×22/7

=2×22

=44 m

NOW THE WHEEL IS 2.5 Km=2.5×1000=2500m

THEN THE NUMBER OF REVOLUTIONS=

2500/44

=56.8 revolutions

~=57
