Question

Jari jari alas suatu kerucut=8cm,dan panjang garis pelukisnya=17cm.tentukan volume kerucut tersebut!

Answer 1

T = √17² -8²
  = √289 -64
  = √225
  = 15 cm
volum = 1/3 x π x r² x t
         = 1/3 x 3,14 x 8 x 8 x 15
         = 3,14 x 64 x 5
         = 1004,8 cm³

Answer 2

T = √17²-8
= √289-64
=√225
= 15

vol = ⅓ × 3,14 × 8² × 15
= 1004,8 cm³
