Tentukan volume tabung jika r=3,5 cm t=15 cm A).volume B).Luas permukaan

A. V = phi × r^2 × t

= 22/7 × 3,5^2 × 15

= 22/7 × 12,25 × 15

= 22 × 1,75 × 15

= 577,5 cm^3



B. L = 2 × phi × r × (r+ t)

= 2 × 22/7 × 3,5 × (3,5+15)

= 2 × 22 × 0,5 × 18,5

= 407 cm^2

A). Volume tabung: phi x r² x t
=22/7 x3,5x3,5x15
=577,5 cm³
B). L. Permukaan=2 x phi x r(r+t)
=2x22/7x3,5(3,5+15)
=407 cm²
