The current san francisco cable railway is driven by two large 14-foot-diameter drive wheels, called sheaves. because of the figure-eight system used, the cable subtends a central angle of 270°on each sheave. find the length of cable riding on one of the drive sheaves at any given time.

Step-by-step explanation:

The problem is about a circular sector, where the angle is 270° and the lenght of the subtended arc is the arc is the unknown variable.

The radius of the drive wheel is

The central angle is 270°.

The length of the arc is

Replacing all values, we have

Thereofre, the length of the cable is around 32.97 feet.

r(0,90)(x,y) . t(-5,0)

last option

step-by-step explanation:

∆def to ∆d"e"f"

- rotate 90 counterclockwise degrees

- then translated 5 to the left (x --> x - 5)

answer is the last option

i got 10.28 but that rounds up to 10.3
