Bab Bangun Ruang
Matematika SMP Kelas VIII

r = d/2
r = 20/2
r = 10 cm

t = √(s² - r²)
t = √(26² - 10²)
t = √(676 - 100)
t = √576
t = 24 cm

Volume gabungan
= volume 1/2 bola + volume kerucut
= (1/2) x (4/3) x π x r x r x r + (1/3) x π x r x r x t
= (2/3) x 3,14 x 10 x 10 x 10 + (1/3) x 3,14 x 10 x 10 x 24
= 2.093,33 + 2.512
= 4.605,33 cm^3
