Tabung
Sisi Tabung
Memiliki 3 sisi : sisi bawah, sisi atas, sisi lengkung (selimut tabung)
Tinggi Tabung (t)
Jarak antara bidang alas dengan alas tutup
Diameter Tabung (d)
Diameter merupakan dua kali jari-jari (d = 2r)
Jari-jari tabung (r)
Jari-jari pada sisi atas dan sisi bawah
5
Unsur-unsur Kerucut :
By: Mrs. Esti
kerucut
Bidang alas berbentuk lingkaran
Diameter alas (d)
Jari-jari alas (r)
Selimut kerucut merupakan sisi lengkung yang menyelimuti kerucut
Tinggi kerucut (t)
Garis Pelukis (s)
6
Unsur-unsur Bola :
By. Mrs. Esti
Bola
Titik Pusat Bola (o)
Jari-jari bola (r)
Diameter bola (2r) dapat disebut tinggi bola
sisi bola adalah sekumpulan titik yang mempunyai jarak sama terhadap titik O

Luas Permukaan Tabung
= 2 x Luas alas + Luas Sisi Tegak
= (2 x π x r2 ) + (2 x π x r x t )
= 2 π r ( r + t )
By: Mrs. Esti
Luas Permukaan Tabung

Luas PermukaanKerucut
= Luas alas + Luas selimut Kerucut
= ( π x r2 )+ ( π x r x s )
= π. r ( r + s)
By: Mrs. Esti
Luas Permukaan Kerucut
10
Luas Permukaan Bola
= 4 x ( π x r2 )
= 4 π r2

Volume Tabung
= Luas alas x Tinggi
= (π. r2 ) x t
= π. r2. t
By: Mrs. Esti
Volume Tabung
13
Volume kerucut
= ⅓ x Luas alas x tinggi
= ⅓ . π. r2 . t
By : Mrs. Esti
volume kerucut
14
Volume ½ bola
=⅓ x volume tabung
=⅓ x π x r2 x t
= ⅓ x π x r2 x 2r
volume 1 bola
= 2 x (⅓ x π x r2 x 2r )
= 4/3 . π . r3
