penyelesaian
diketahui
tabung
r=3,5dm
t=10dm
kerucut
r=3,5
t=6dm
ditanya
volume...?
jawab
V1= πr²t
=22/7×3,5²×10
=22/7×12,25×10
=385dm³
V2=1/3πr²t
=1/3×22/7×3,5²×6
=1/3×22/7×12,25×6
=77dm³
V.gabungan = V1+V2
=365+77
=462dm³ ✅
semoga membantu ◉‿◉
Volume = V1 + V2
Volume = (πr2t) + (⅓ × π × r × r × t)
Volume = (22/7×3,5^2×10) + (1/3×22/7×3,5×3,5×6)
Volume = (22/7×12,25×10) + (1/3×22/7×12,25×6)
Volume = (38,5×10) + (1/3×38,5×6)
Volume = (385 dm3) + (12.83×6)
Volume = 385 dm3 + 77 dm3
Volume = 462 dm3
