Tentukan volume & luas permukaan tabung dengan: r=4,75cm . t=10cm jawab plisss T__T

V = phi × r^2 × T

= 3,14 × 4,75^2 × 10

= 3,14 × 4,75 × 4,75 × 10

= 708,47 cm^3


L = 2 × phi × r^2 + 2 × phi × r × T

= 2 × 3,14 × 4,75^2 + 2 × 3,14 × 4,75 × 10

= 2 × 3,14 × 22,56 + 298,3

= 141,68 + 298,3

= 439,98 cm^2
