Answer:
B
Step-by-step explanation:
Answer: 5 yards
Step-by-step explanation:
1. Look at the vertical parts of the drawing from right to left
2. Notice that the longest vertical part is 11 yards
3. Notice that the other labels vertical part is 6 yards
4. Notice that the third vertical part, the one with the ? is 11 yds - 6 yds since the two shorter vertical parts would make a line as long as the longest vertical part of they were put together. Since this is the case the missing part is 11 yds-6 yds = 5 yds.
The radii to the points of tangency in each circle are parallel. Connecting the tangent point of the smaller circle to the corresponding radius of the larger circle creates a right triangle with hypotenuse 16 +4+6 = 26 and leg 16 -6 = 10. These numbers let you find the straight length between wheels as
.. √(26^2 -10^2) = 24
The minor arc of belt around the smaller wheel is 2*arccos(10/26) = 2.35201 radians. Then the major arc of belt around the larger wheel is
.. 2π -2.35201 = 3.93117 . . . radians
Of course, the length of each arc is the product of radian measure and radius. Then the total belt length is
.. (16 cm)(3.93117 radians) +(6 cm)*(2.35201 radians) +2*(24 cm) = 125 cm
