Ответ:
yes
step-by-step explanation:
given :
larger gear has a diameter of 4 inches
smaller one has a diameter of 2 inches
to find : circumference of the larger gear is 2 inches more than the circumference of the smaller gear. do you agree?
solution :
diameter of larger gear is 4 inches
so, radius =
so, radius of larger gear =
thus radius of larger gear is 2 inches
now, diameter of smaller gear is 2 inches
so, radius of smaller gear =
thus radius of smaller gear is 1 inch
now formula of circumference of circle :
so, circumference of larger gear =
=
circumference of smaller gear =
=
hence the circumference of larger gear is more than the circumference of the smaller gear.
