Determine if the given differential equation is exact (e^2y-y cos xy)dx+(2xe^2 y-cos xy+2y)dy=0

rewona [7]

$\dfrac\partial{\partial y}\left[e^{2y}-y\cos xy\right]=2e^{2y}-\cos xy+xy\sin xy$

$\dfrac\partial{\partial x}\left[2xe^{2y}-y\cos xy+2y\right]=2e^{2y}+y\sin xy$

The partial derivatives are not equal, so the equation is not exact.

What is the volume of a cylinder with a diameter of 12 in. and a height of 7 in.?

Stels [109]

Answer

Find out the volume of a cylinder .

To prove

Formula

$Volume\ of\ cylinder = \pi r^{2}h$

Where r is the radius and h is the height.

As given

Diameter of 12 in. and a height of 7 in.

$Radius = \frac{Diameter}{2}$

$Radius = \frac{12}{2}$

Radius = 6 in

$\pi = 3.14$

put all the values in the formula

$Volume\ of\ cylinder = 3.14\times 6\times 6\times 7$

= 791.28 in³

Therefore the volume of the cylinder is 791 .28 in³ .
