r ( jari - jari ) =
t ( kerucut ) = 13 cm
t.total = 25
maka
tinggi bola = jari jari = 5 cm
sisi miring kerucut = 13^2 - 5^2
= 169 - 25
= 144 --> diakar 144 = 12 cm
tingi tabung = 25 - ( 12+ 5 )
= 8 cm
maka V = πr²t + 1/3πr²t + 1/2 . 4/3 πr³
= 3,14 * 5² * 8 + 1/3 *3,14 * 5² * 12 + 2/3 * 3,14 * 5³
= 628 + 314 + 261,7
= 1.203 , 7 Cm
jawab: B

=
tingi tabung = T.Total - ( T.Kerucut + 1/2 T.Bola)
= 25 - ( 12 + ( 1/2 * 10 ) )
= 25 - ( 12 + 5 )
= 25 - 17
= 8 cm
maka Vtotal = Volume Kerucut + Volume Tabung + Volume Bola
1.203,7 CM
jawab: B
