s/ garis pelukisnya= 25
π = 22/7
dit ; tinggi(t) = ..?
Volume(V) = …?
jawab..
pke triple phytagoras, utk mencari tinggi kerucut:
3, 4, 5
5, 12, 13
7, 24, 25 ===>>> nah,,ini yg d pke
8, 15, 17
20, 21, 29
jadi,,tinggi nya= 24 cm
V= 1/3 π r²
= 1/3 x 22/7 x7²
= 1/3 x 22/7 x 49==> [ 49:7 =7]
= 1/3 x 22 x 7
= 51,3 cm³
semoga bermanfaat::)
= 1/3 x 22/7 x 7² x 24 t² = 25²-7²
= 1232 cm³ t² = 625-49
t = √576 =24 m
