Answer:
The answer to your question is 8 h
Step-by-step explanation:
Data
length of the ladder = 200 cm
distance between each rung = 20 cm
rate = 10 cm/h
fifth rung = ?
Process
1.- Calculate the total distance the tide must rise
distance = 20 cm x 4
= 80 cm because the first rung touches the water
2.- Calculate the time
rate = distance / time
-Solve for time
time = distance / rate
-Substitution
time = 80 cm / 10cm/h
-result
time = 8 h
The formula for the height of a cylinder is h = V / (π.r²) and the height of a cylinder with a volume of 36 cm³ and a radius of 3 cm is 4/π cm
Given a cylinder with a radius r and height h, then its volume is given by the formula:
V = π.r².h
Where:
V = volume
r = radius
h = height
To find the formula for the height, divide both sides by π.r²
V : π.r² = π.r².h : π.r²
or,
h = V / (π.r²)
The given parameters are:
V = 36 cm³
r = 3 cm
Substitute those parameters into the formula:
h = 36 / (π.3²)
h = 36 / (9π)
h = 4/π cm
