Step-by-step explanation:
Answer:
a) r(t) = 0.783t radians
b) h(t) = 30cos(0.783*t) feet
Step-by-step explanation:
The situation is depicted in the picture attached
<h3>(see picture)
</h3>
Since the angular speed is constant, to find an expression for the angle r(t) in radians we just cross-multiply using the fact that 1 min = 60 seconds
4.7 radians __________ 60 seconds
r(t) radians ____________ t seconds
The height h(t) after t seconds is given by
h(t) = 30cos(r(t)) ===>
h(t) = 30cos(0.783*t) feet
Answer:
you do a line that goes through b but doesn't go through the circle
Easy 5+4=9+8=17 your answer is 17 :)
Answer:
V=( 1/6 )* π * d³
Step-by-step explanation:
We khow that d= 2r⇒ r=d/2
- so r³= d³/8
- substitute r with d³/8
- V= (4/3)*π*(d³/8) = (4/3*8)*d³*π = (1/6 )* d³ *π
