volume kerucut yang keliling alasnya 44 cm , garis pelukisnya 25 cm , dan π =22/7 adalah

Keliling alas = nd
44 = 22/7 x d
d = 44 : 22/7
d = 44 x 7/22
d = 14 cm

r = 1/2d
= 7 cm


t = V s^2 - r ^2
= V 625 - 49
= V576
= 24 cm


Volume Kerucut||

1/3 n r^2 t
= 1/3 x 22/7 x 49 x 24
= 22/21 x 49 x 24
= 1232cm^2

V = akar
n = phi
