Question

1)Volume tabung 3696
Tinggi 6
Hitung lp?
2)lp 616
Hitung jari" bola dan v bola

Answer 1

Vtbg=3,14 .r kuadrat . 6
3696=3,14 . r^2 .6
3696=18,85 .  r^2
r^2 = 3696 / 18,85 = 196
r =

Answer 2

1.di tanya Lp????
v=π×r²×t
3696=22/7×r²×6
3696×7=22×6×r²
25872=132r²
r²=25872/132
r²=169
r=√169
r=14
Lp=2×π×r(t+r)
   =2×22/7×14(6+14)
   =88×20
Lp=1760cm²
