Sagot :
Answer:
Let r represent the radius of the smaller circle and R the radius of the larger circle.
Apply ratios: the radius of smaller circle to radius of larger circle, i.e.
r: R = 3 : 7.
I complete rotation = 360 degrees.
Part 1:
For one complete rotation of the smaller circle, the larger circle is rotated through: (3/7)*(360) = 154.3 degrees
Part 2:
For one complete rotation of the larger circle, the larger circle is rotated through: (7/3)*(360) = 840.0 degrees
This is equivalent to (840/360) = 2.3 rotations
Alternatively, use the ratios:
The number of rotations = R/r = 7/3 = 2.3 rotations

Answer:
Step-by-step explanation:
for smaller gear circumference=2π×2=4π inches
for larger gear
l=4π
θ=l/r
θ=(4 ×180)/7=720/7=102 .9°
for larger gear circumference=2π×7=14π
number of rotations=(14π)/4π=7/2=3.5 rotations or 3 1/2 rotations.
