Solve, using linear combination.
Bingel [31]

Multiply the first equation by -1 to get  -4x - y = --5

Then add the second equation               3x + y = 3    

                                                           + ____________  

                                                                  -x = -2  or x = 2


then plug in 2 for x in one of the equations and solve for y      4(2) + y = 5  

                                                                                                          8 + y = 5

                           Subtract 8 from both sides                                        y = -3


                             So x = 2, y = -3     or (2,-3)

The diameter of a cylinder is 3yd the height is 8yd
nalin [4]

Answer:

volume= 56.55 yds

Step-by-step explanation:

If you're looking for the volume, the formula is V=\pi r^{2} h.

Diameter is two times the radius (radius is half of the diameter) so the radius of the cylinder would be 1.5 yds.

After you've gotten that information, plug those values into the formula.

V=\pi 1.5^{2} 8

Solve 1.5^2 first. Then multiply that value by pi. Then multiply that value by the height which is 8yds.

Volume=56.55yds rounded to the nearest hunderedth.
