2nd cylinder: 439.6 square cm

Answer 2

1st cylinder: 3541.9 square mm

2nd cylinder: 439.6 square cm

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`
