One cylinder has two bases and one side, and the side is a rectangle.

So S = 2*base + side

S = 2* (pi*27^2) + (2*pi*27*37) = 3456pi

Find the points of intersection of the lines 10x−4y=2 and 2x+8y=7 without graphing.

Jet001 [13]

Answer:

$x=\frac{1}{2},y=\frac{3}{4}$

Step-by-step explanation:

Given:

$10x-4y=2 ,2x+8y=7$

To find: points of intersection of the given lines

Solution:

In substitution method, the system of equations is solved by expressing one variable in terms of another, as a result, removing one variable from an equation.

$10x-4y=2 \\2(5x-2y)=2\\5x-2y=1\\5x=1+2y\\x=\frac{1+2y}{5}$

Put $x=\frac{1+2y}{5}$ in the equation $2x+8y=7$

$2x+8y=7\\2[\frac{1+2y}{5}]+8y=7\\ 2+4y+40y=35\\44y=35-2\\44y=33\\y=\frac{33}{44}\\ =\frac{3}{4}$

Put $y=\frac{3}{4}$ in the equation $x=\frac{1+2y}{5}$

$x=\frac{1+2y}{5}\\=\frac{1}{5}[1+2(\frac{3}{4})]\\=\frac{1}{5}[1+(\frac{3}{2})]\\\\=\frac{1}{5}(\frac{2+3}{2}) \\\\=\frac{1}{5}(\frac{5}{2})\\\\=\frac{1}{2}$

Therefore,

$x=\frac{1}{2},y=\frac{3}{4}$

Can every parallelogram be changed into a rectangle<br> with equal area? Explain.

jeka94

Answer:

Every parallelogram can be made into a rectangle, which is why we use the same formula to find the area of a parallelogram and a rectangle.

Step-by-step explanation:

Because the parallelogram and rectangle are composed of the same parts, they necessarily have the same area.
