tolong jawab ya kak mau di kumpulin jam 3 nanti.
V = V tabung - V kerucut
= (π × r × r × t) - (⅓ × π × r × r × t)
= (22⁄7 × 14 × 14 × 35) - (⅓ × 22⁄7 × 14 × 14 × 35)
= 2.1560 - 7186.67
= 14.373,33 (C)
volume : v1. - v2.
volume 1. (tabung) : π × r² × t
v = [tex]\frac{22}{7}[/tex] × 14² × 35
v = [tex]\frac{22}{7}[/tex] × 14 × 14 × 35
v = 2.156,0
volume 2. (kerucut) :
v = [tex]\frac{1}{3}[/tex] × π × r² × t
v = [tex]\frac{1}{3}[/tex] × [tex]\frac{22}{7}[/tex] × 14 × 14 × 35
v = 7.186,67
volume : v1. - v2.
v = 2.156,0 - 7.186,67
v = 14.373,33 atau opsi c.
