tinggi kerucut = √sisi miring kercut² - sisi samping kerucut²
= √26² - 10²
= √676 - 100
= √576 = 24 cm
Volume kerucut
1/3 π r² t = 1/3 π 10² 24
= 800π
volume bola
4/3 π r³ = 4/3 π 10³
= 4000π/3
karena yang dibutuhkan setengah dari volume bola
maka,
4000π/3 : 2 = 2000π/3
sehingga volume total = 800π + 2000π/3
= 800 (3,14 ) + 2000(3,14)/3
= 2512 + 2093,33
= 4605,33 =>A
volum setengah bola = 1/2 .4/3 π r³ =1/2 . 4/3 . 3.14 . 10.10.10 = 2093,33
volum kerucut = 1/3 .La . t = 1/3 . 314 . 24 = 2512
volum total = 2512 + 2093,33 = 4605,33 (a)
