the Answer:
Step-by-step explanation:
To find the area of a rectangle, you have to multiply the two sides by each other. In this case, the two sides are , and Multiply these together. You can make it easier by turning it into an improper fraction by multiplying the whole number (2 on the left) by the denominator (2 on the bottom) and adding it to the numerator (1), so you get . Now just multiply by . which is , which can be simplified into

Answer:
0.43 ft/hr
Step-by-step explanation:
dv/dt = 15ft³/hr
Height = 10ft
We are required to get dh/dt
h = 3r
r = h/3
Formula for volume = 1/3πr²h
We put value of h
1/3π(h/3)²h
= 1/3π(h²/9)h
= 1/3πh³/9
= πh³/29
dv/dt = 1/27π.3h²dh/dt
= dv/dt = πh²/9dh/dt
Remember dv/dt = 15
When we put this in we get
dh/dt = 15x9/3.142x10²
= 135/314.2
= 0.43 ft³/hr
