Question 1156284: The restaurant at the top of a very tall building in Seattle rotates 0.94 revolutions every hour. Karla sits 19.2 meters from the center of the restaurant near a window.
(a1) Through how many radians does Karla turn in 101 minutes?
(exact) angle =
rads

Enter the exact answer; use pi for
π
.
(a2) Now, report the answer accurate to 3 decimal places:
(approximate) angle =
rads
(b1) How far does Karla move in 101 minutes?
(exact) distance =
meters

Enter the exact answer; use pi for
π
.
(b2) Now, report the answer accurate to 1 decimal place:

0.94/60=x/101
cross-multiply and 60x=101*.94=94.94
x=94.94/60=1.582 revolutions or 1.582*2pi=3.164 pi radians
9.942 radians
The distance is 2 pi* 19.2*1.582=60.749 pi meters
This is 381.7 feet.
