Question

Christian missionary camp

Answer 1

Part 1: the entire clock face has 60 minutes on it, and since it's a circle, it's 360 degrees

degrees per minute = # of degrees/# of minutes = 360/60 = 6 degrees per minute

between 1:25 and 1:50 that's 25 minutes passed, so take 15 minutes * 6 degrees per minute = 90 degrees

then convert 90 degrees to radians by multiplying 90 * (pi/180)

part 2: "how far does the tip travel" that's another way of asking for arc length

arc length = radius * angle

where the radius = 4 inches [the length of the minute hand] and angle is the solution from part 1

Answer 2

sorry just had to make a small correction

let me know if something was unclear

Answer 3

oh that's right, should be 25*6

Answer 4

yes

Answer 5

well they'd probably want you to simplify 150 * (pi/180) to 5pi/6

Answer 6

yes
