Need help with solving a 2x2 system of linear equations<br><br> PLEASE HELP ME
Yakvenalex [24]
\bf \begin{array}{llll}&#10;-5x-y=5\\&#10;-5x+y=5\\&#10;-------\\&#10;-10x+0=10&#10;\end{array}\implies -10x=10\implies x=-1

so if x = -1, let's plug that in the second equation

-5(-1)+y = 5

A Right Cylinder has a radius of 3 cm and a height of 5 cm.
Shtirlitz [24]

Answer:

V = 141.37 cm³

Surface area = 150.80 cm²

i. Doubling the radius to 6 cm, while the height remains 5

Step-by-step explanation:

Given that :

Radius, r = 3cm

Height, h = 5cm

Volume , V of right cylinder :

V = πr²h

V = π * 3² * 5

V = 141.37166

V = 141.37 cm³

Surface Area :

2πr(h + r)

2 * π * 3(3 +5)

18.849555(8)

150.79644

= 150.80 cm²

Volume at r = 6 ; h = 5

V = π * 6² * 5

V = 565.48667 cm³

Volume at r = 3 ; h = 15

V = π * 3² * 15

V = 424.11500 cm³

To increase volume,
