Sobat pernah melihat drum minyak atau kaleng susu? Kedua benda tersebut berbentuk tabung. Tabung terbentuk dari 2 buah lingkaran dan sebuah segi empat (bisa persegi/persegi panjang). Berikut rumus tabung

Rumus Volume Tabung

Volume = ∏ r² t

Phi = 3,14 atau 22/7
r = jari-jari alas
t = tinggi tabung

Rumus Luas Selimut Tabung

Coba amati gambar di atas, ternyata selimut tabung merupakan segi empat antara keliling alas (bentuk lingkaran) dan tinggi. Jadi dapat dinyatakan bahwa rumus tabung untuk luas selimutnya merupakan perkalian antara keliling alas dengan tinggi

Luas Selimut = Kll Lingkaran x t = 2∏ r x t

Rumus Luas Permukaan Tabung

Menghitung luas permukaan tabung itu sama dengan kita menjumlahkan luas selimut dengan luas 2 buah lingkaran. Perhitungannya sebagai berikut

Luas Permukaan = Luas Selimut + 2 Luas Lingkaran
= 2∏ r x t + 2∏ r²= 2∏ r (t+r) atau 2∏ r (r+t)

Ryuki had two separate S.I.C. Hero Saga side stories published in Monthly Hobby Japan magazine. The first was titled Masked Rider Ryuki: Advent Calendar (MASKED RIDER RYUKI -アドベントカレンダー- Kamen Raidā Ryūki: Adobento Karendā^?) and featured original characters Kamen Rider Ouja Survive (仮面ライダー王蛇サバイブ Kamen Raidā Ōja Sabaibu^?) and his Mirror Monster the Genosurviver(ジェノサバイバー Jenosabaibā^?). The second S.I.C. Hero Saga story Masked Rider Ryuki: World of If (MASKED RIDER RYUKI -IFの世界- Kamen Raidā Ryūki: Ifu no Sekai^?) is an alternate telling that features Ouja Survive from Advent Calendar and also introducesKamen Rider Ryuga Survive (仮面ライダーリュウガサバイブ Kamen Raidā Ryūga Sabaibu^?). Advent Calendar ran from August to December 2004 and World of If ran from June to August 2005.

Kamen Rider Ryuki: Ryuki vs Kamen Rider Agito (仮面ライダー龍騎 龍騎vs仮面ライダーアギト Kamen Raidā Ryūki: Ryūki Buiesu Kamen Raidā Agito^?) is the Ryuki Hyper Battle Video. It features Shinji Kido having a dream where he joins up with Kamen Riders Knight, Zolda, and Ouja, all of whom who are acting out of character, to fight an evil Kamen Rider Agito in the Mirror World. They are soon joined by the real Kamen Rider Agito who helps defeat his evil doppelganger.

Kamen Rider Ryuki: Episode Final (劇場版　仮面ライダー龍騎　ＥＰＩＳＯＤＥ　ＦＩＮＡＬ Gekijōban Kamen Raidā Ryūki Episōdo Fainaru^?) is an alternate ending to the series, taking place after the events of episode 46. With only six Riders remaining in the Rider War; Ryuki (Shinji Kido), Knight (Ren Akiyama), Zolda (Shuichi Kitaoka), Ouja (Takeshi Asakura), and Femme (Miho Kirishima); Shirō Kanzaki alerts them to quickly settle the Rider War within three days. One of them must win and become the last survivor before the sixth surviving Rider reveals himself. Amidst the impending chaos of the fight between the Riders, Shinji discovers an unbelievable truth about the relationship between Yui Kanzaki and the Mirror World, as well as discovering the existence of his Mirror World doppelganger, Kamen Rider Ryuga.

13 Riders[edit source | editbeta]

Kamen Rider Ryuki Special: 13 Riders (仮面ライダー龍騎スペシャル 13RIDERS Kamen Raidā Ryūki Supesharu Sātīn Raidāzu^?) was written by Toshiki Inoue and directed by Ryuta Tasaki. It features the debut of the thirteenth Kamen Rider in the continuity of Ryuki:Verde. This special was first broadcast on TV Asahi on September 19, 2002.^[1][2] It was later released on DVD on July 21, 2003.^[3] The DVD also featured information on the characters, an interview with actor Arthur Kuroda, and an "interview" with some of the characters.

This television special is an alternate telling of the Kamen Rider Ryuki story. Shinji Kido's life, working as an employee at ORE Journal, takes a sharp turn after being pulled into the Mirror World by a Mispider. Luckily, he was saved by a Kamen Rider, Ryuki (Koichi Sakakibara, portrayed by Keiichi Wada). However, Sakakibara could no longer go on due to the severity of his injuries and passed his Card Deck to Shinji, allowing him to become the next Ryuki and defeat the monster. After meeting with Yui Kanzaki and Ren Akiyama (Kamen Rider Knight), Shinji learns about the conditions of the Rider War, as well as of the other Riders participating. Unable to allow such a game of death to exist like his Rider predecessor, Shinji sets out to convince all the Riders to end the senseless fighting and put an end to the War. His pleas fall upon deaf ears as just about every other Rider (except for the already-defeated Riders Raia and Scissors) sets out to hunt down Shinji and his eventual reluctant ally, Ren. Eventually, Shinji's deck is destroyed and Ren dies, after passing on the deck for Kamen Rider Knight to Shinji. The special has two different endings which were voted on by the viewers via phone at the time of the initial airing: the voted-for-air ending (in which Shinji faces the surviving Riders on his own) and the alternate ending (a resetting of the Rider War).
