Find the surface area of the cylinder. Use 3.14 for pi . a hay bale with a diameter of 30 inches and a height of 72 inches about

valentina_108 [34]

Surface Area of cylinder = 8195.4 inches^2

Step-by-step explanation:

we are given:

Diameter of cylinder = 30 inches

Height of cylinder = 72 inches

We need to find:

Surface area of cylinder = ?

The formula used is:

$Surface\,\,Area=2\pi rh+2\pi r^2$

We know radius = diameter/2

so, radius = 30/2 = 15 inches

putting values:

$Surface\,\,Area=2\pi rh+2\pi r^2\\Surface\,\,Area=2*3.14*15*72+2*3.14*(15)^2\\Surface\,\,Area=6782.4+1413\\Surface\,\,Area=8195.4$

So, Surface Area of cylinder = 8195.4 inches^2

Solve the following system of equations. State whether the system is consistent and independent, consistent and dependent, or in

Makovka662 [10]

Answer:

Inconsistent

Step-by-step explanation:

If a system has at least one solution, it is said to be consistent.

If a consistent system has exactly one solution, it is independent.

If a consistent system has an infinite number of solutions, it is dependent.

A system of equations is called an inconsistent system of equations if there is no solution.

Given the system of two equations

$\left\{\begin{array}{l}-4x+7y=28\\ \\4x-7y=32\end{array}\right.$

Add these two equations:

$(-4x+7y)+(4x-7y)=28+32\\ \\-4x+7y+4x-7y=60\\ \\(-4x+4x)+(7y-7y)=60\\ \\0=60$

This is false statement, hence, the system of two equations has no solution and is inconsistent.
