Step-by-step explanation:
Answer:
h = 135/(4π)
Step-by-step explanation:
The formula for the volume of a cone is V = (1/3)πr²h,
where r is the radius, and h is the height. We need to use the given info and this fomula to find h.
Step 1: We are told that V = 45, and r = 2, so plug those values in
45 = (1/3)π(2²)h
Step 2: Solve for h
Simplify...
45 = (1/3)π(4)h (2² = 4)
45 = (4π/3)h (commutative property of multiplication)
Multiply both sides of the equation by 3/(4π) to isolate h
[3/(4π)](45) = [3/(4π)](4π/3)h
135/(4π) = h { [3/(4π)](4π/3) simplifies to 1 }
A. To solve for the time it takes for the package to
strike the ground, all we have to do is to plug in the given values in to the
position equation:
s = −16 t^2 + v0 t + s0
Where,
<span>s = distance of the plane from the ground = - 6000 ft (negative since the package moves from
top to bottom)</span>
t = time for it to strike the ground = unknown
v0 = 0 since the package starts from rest
s0 = 0 since we take the plane as the reference point
Substituting the given values:
- 6000 = -16 t^2 + 0 * t + 0
16 t^2 = 6000
t^2 = 375
t = 19.36 s
B. s = v * t
where v = 600 miles / hr = 0.17 miles / s
s = (0.17 miles / s) * 19.36 s
s = 3.23 miles = 17,054 ft
