jalan mencari luas dan volume tabung tinggi 7 cm lebar15cm

Luas permukaan tabung
= 2 x π x r ( r + t )
= 2 x 22/7 x 7 cm ( 7 cm + 15 cm )
= 44 cm x 22 cm
= 968 cm²

Volume 
= π x r² x t
= 22/7 x 7 cm x 7 cm x 15 cm
= 2.310 cm³

luas permukaan = (2.π.7.7)+(π.d.15)
(2.22/7.7.7)+(22/7.14.15)
(2.22.7)+(22.30)
308+660
968 cm²
volume = π.7.7.15
22/7.7.7.15
