2. volume kerucut 462 m3, jari2 kerucut 7 m. hitung tinggi kerucut!
responsible as soon as possible, huh? thanks before.

Answer 1

1. volume= 1/3 x π x r² x t
   616     = 1/3 x 22/7 x r² x 12
616*3*7  = 22 x r² x 12
12936    = r² x 264
√(12936:264)= r
√49 = r
7 cm
2.  462 = 1/3 * 22/7 * 7² x t
    462*3*7= 22 x 49 x t
9702=1078 x t
9 cm=t
