Panjang jari” alas kerucut 14 cm dan garis pelukisnya 25 cm hitung luas permukaan nya​

Diameter = 14 cm

Jari-Jari

= 1/2 x diameter

= 1/2 x 14

= 7 cm

Tinggi Kerucut

= √(s² – r²)

= √(25² – 7²)

= √(625 – 49)

= √576

= 24 cm

Maka, Volume Kerucut

= 1/3 πr² x t

= 1/3 x 22/7 x 7² x 24

= 22/3 x 7 x 24

= 22 x 7 x 8

= 1.232 cm³
