Question

Tolooong dooong. sama cara nya juga yaaa.

Answer 1

R = (v2 - 1)/(v2 + 1)
r = (v2-1)/(v2+1) . (v2-1)/(v2-1)
r = (v2 - 1)^2 = 3 - 2v2

volume tabung
= pi r^2 t
= pi (3 - 2v2)^2 . 6v3/(2v2+3)
= pi (3 - 2v2)^2 . 6v3/(2v2+3) . (3-2v2)/(3-2v2)
= pi (3 - 2v2)^3 . 6v3
= pi (27 - 54v2 + 72 - 16v2) . 6v3
= pi (99 - 70v2) . 6v3
= (594v3 - 420v6) pi
