Question

No 15 abc tolong bantu jawab kak, trims

Answer 1

A. L besar/ L kecil = tinggi besar / tinggi kecil
96 phi / 12 phi = 12 / x
96 / 12 = 12 / x
x = 12 . 12 / 96 = 1,5

L kecil = 12 phi
phi . r^2 = 12 phi
r^2 = 12
r = √ 12 = 3,46


b. V kecil / V besar = d kecil / d besar
12 phi / 324 phi = 8 / x
12 / 324 = 8 / x
x = 324 . 8 / 12 = 216

V besar = 1/3 . L alas . t
324 phi= 1/3 . phi . r^2 . t
324 = 1/3 . 108^2 . t
324 = 3888 . t
t = 3888 / 324 = 12

s^2 = t^2 + r^2
s^2 = 12^2 + 108^2
s^2 = 144 + 11664
s^2 = 11808
s = √ 11808 = 108,67
