Volume bangun tersebut adalah... tolong dibantu ya

r=15
tinggi kerucut = phytagoras = 15,36,39 tingginya 36
V.kerucut = 3,14 x 15 x15 x 36 : 3
= 3,14 x 225 x 12 = 8.478 cm^3
V.1/2bola =1/2. 1/6 x 3,14 x 30 x30 x30
= 3,14 x 4.500 : 2 = 14.130:2 =7.065 cm^3
volume bangun=8.478 + 7.065= 15.543 cm^3 (A.)

semoga membantu

V1/2 bola = 2/3.phi.r^3
=2/3.3,14.15.15.15
=7065

V kerucut = 1/3.phi.r^2.tk
tk^2 = 39^2-15^2= 1521-225 =1296
Tk = akar dari 1296 = 36
Vk= 1/3.3,14.15^2.36
Vk= 12.3,14.225
Vk=8478

Vseluruhnya =7065+8478
=15543
