In a coordinate point, the values would go (x,y). Substitute the x and y values from the coordinate points into the equation given.
8(3)+B(4)=40

Multiply 8x3
24+B(4)=40

Subtract 24 from both sides

4B=16

Divide the whole equation by 4

B=4

Step-by-step explanation:

The volume of the conical pile is given by

$V = \dfrac{\pi}{3}r^2h$

Taking the derivative of V with respect to time, we get

$\dfrac{dV}{dt} = \dfrac{\pi}{3}\dfrac{d}{dt}(r^2h)$

$\:\:\:\:\:\:\:= \dfrac{\pi}{3}\left(2rh\dfrac{dr}{dt} + r^2\dfrac{dh}{dt}\right)$

Since r is always equal to h, we can set

$\dfrac{dr}{dt} = \dfrac{dh}{dt}$

so that our expression for dV/dt becomes

$\dfrac{dV}{dt} = \dfrac{\pi}{3}\left(3r^2\dfrac{dh}{dt}\right)$

$\:\:\:\:\:\:\:= \pi r^2\dfrac{dh}{dt}$

Solving for dh/dt, we get

$\dfrac{dh}{dt} = \dfrac{1}{\pi r^2}\dfrac{dV}{dt}$

$\:\:\:\:\:\:\:= \dfrac{1}{9\pi\:\text{m}^2}(36\:\text{m}^3\text{/s})$

$\:\:\:\:\:\:\:= \dfrac{4}{\pi}\:\text{m/s}$

An oblique cylinder has a diameter of 14 units. The volume of the cylinder is 1,176π cubic units.

Kaylis [27]

Answer:

24 units

Step-by-step explanation:

The volume of the cylinder = πr²x

Where r is the radius of the base and x is the height of the cylinder.

πr²x = 1,176π

π×(14/2)²x = 1,176π

dividing by π both sides,

(14/2)²x = 1,176

7²x = 1,176

49x = 1,176

x = 1,176/49

= 24 units
