Answer 1

Two gears are connected and are rotating simultaneously. The smaller gear has a radius of 2 inches, and the larger gear has a radius of 8 inches.

two circles touching at one point. Larger circle has radius of 8 inches. Smaller circle has radius of 2 inches.

Part 1: What is the angle measure, in degrees and rounded to the nearest tenth, through which the larger gear has rotated when the smaller gear has made one complete rotation?

Part 2: How many rotations will the smaller gear make during one complete rotation of the larger gear?

Answer 2

I medal and fan !!!!

Answer 3

circumference = 2 * pi * r one rotation use r = 2

angle /360 = length/ circumference

equate the length of the arc for the large circle with the circumference of the small circle
here the radius = 8 solve for angle

ratio of circumferences

Answer 4

the cir for small is 12.56 and for the big one is 50.24 right
