Bangun Ruang KerucutLingkaran diameter 20 cm
Keliling alas kerucut = 3/4 keliling lingkaran
r kerucut = 3/4 r lingkaran
rk = 3/4 (1/2)(20) = 7,5 cm
S kerucut = R lingkaran
S = 1/2(20)= 10 cm
t kerucut = √(s² - rk²)
tk = √(10² -7,5²)= 6,6
Volume Kerucut = π r² t
Vk = 3,14 x (7,5)² x (6,6)
Vk = 1.165,725 cm³
