Answer:
The height is 4cm
Step-by-Step Explanation:
Use the formula:
V= π (d/2)² h
Solve for h
h=(V/π(d/2)²
804.25/(π (16/2)²
4cm

Based on the graph shown, the intersection is (1.231, -0.452). 1.231 acts as coordinate x of the intersection, and -0.452 acts as coordinate y of the intersection.
In the equation

the solution is the value of x. So the solution of the equation is the value of x. So, we use coordinate x of the intersection to find the solution of the equation, that is 1.231.
Final answer: 1.231
60% or 3/5 of the tank will be filled in an hour.
The pump will fill 2/5 of the tank in 2/3 hours.
In order to find out how much of the tank will be filled in an hour, use direct proportion and assume portion of the tank that will be filled up in an hour is x.
<em>2/5 of tank : 2/3 hours </em>
<em>x of tank : 1 hour </em>
Cross multiply to get:
2/3x = 2/5
x = 2/5 ÷ 2/3
x = 2/5 x 3/2
= 0.6 of the tank
= 60%
= 3/5 of tank
In conclusion, 60% of the tank will be filled in an hour.
