Hitunglah volume kerucut yg panjang garis pelukisnya 17cm dan diameternya 16cm

s = 17 cm
d = 16 cm
r = 8 cm

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

Volume
= 1/3 x π x r² x t
= 1/3 x 3,14 x 8 cm x 8 cm x 15 cm
= 1.004,8 cm³

t = akar (17^2 - 8^2)
= akar ( 289 - 64)
= akar 225
= 15 cm

volume = 1/3 × phi × r^2 × t
= 1/3 × 3,14 × 8^2 × 15
= 3,14 × 64 × 5
= 3,14 × 320
= 1004,8 cm^3
