Sekalian pake caranya. makasih

Answer 1

33)
d tab = 21---> r tab = 21/2
t1 = 15 cm
r bola =rb =  7

tinggi air naik = t2= volume 3 bola / luas alas tabung
t2 = 3 (4/3)(π)(rb)³ / π (r tab)²
t2 = 4 (rb)³ / (rtab)²
t2 = 4 (7³)/(21/2)² =  (4 .7.7.7.2.2..)/(21.21..) = 112/9=12,44

tinggi air dalam tabung sekarang = t1+t2 = 15 +12,44 = 27,44
