12.320=3,14×15×r kwadrat
12.320=1/3×47,1 ×r kwadrat
12.320=15,7 × r kwadrat
r kwadrat =12 320 ÷15,7=785 (hasil di bulat kan)
r =akar 785 = 28
(2) V=1.004.800 liter
r=80 dm
dit = T
(dm=liter)
1.004.800=1/3 ×3,14×80×80×T
1.004.800=1/3×3,14×6400×T
1.004.800=1/3×20.096×T
1.004.800=6.698×T
T=1.004.800÷6.698
=150
(maaf jika salah..semoga bisa membantu)
