Answer:

1st cylinder: 3541.9 square mm

2nd cylinder: 439.6 square cm

Step-by-step explanation:

s = 2\pi r^{2} + 2\pi rh\\s = 2(3.14)(12)^{2} + 2(3.14)(12)(35)\\s = 6.28(144) + 6.28(420)\\s = 904.32 + 2637.6\\s = 3541.92\\s = 3541.9

Second cylinder.

s = 2\pi r^{2} + 2\pi rh\\s = 2(3.14)(7)^{2} + 2(3.14)(7)(3)\\s = 6.28(49) + 6.28(21)\\s = 307.72 + 131.88\\s = 439.6

Step-by-step explanation:

When an equation is just x=a number, it is a horizontal line.

When the equation is just y=a number, it is a vertical line.

If the equation is the full y=mx+b, it is oblique.

2x=5

x=2.5

vertical

y+2=-1

y=-3

horizontal

x+y=3

y=-x+3

oblique
