diameter alas kerucut 16 cm dan panjang garis pelukisnya 17 cm Tentukan volume kerucut jika Π:3.14

V = ⅓ . 3,14 . 8 . 8 . 15
V = 1004,8 cm³

Kerucut

r = d/2
r = 16/2
r = 8 cm

t = √(s² - r²)
t = √(17² - 8²)
t = √(289 - 64)
t = √225
t = 15 cm

Volume = (1/3) x π x r x r x t
Volume = (1/3) x 3,14 x 8 x 8 x 15
Volume = 1.004,8 cm^3
