Question

Jika Di Ketahui Tinggi Kerucut 7 Cm Dan Volume Kerucut 264Cm³ . Hitunglah Jari Jari Kerucut Tersebut !

Answer 1

Volume kerucut = 1/3 π r^2

1/3 22/7 r^2 = 264
r^2 = 264 x 3 x 7 : 22
r^2 = 252
r = 15.8 cm

Answer 2

V kerucut=1/3.pi.r2.t
264=1/3.3,14.r2.7
264= 7,327.r2
r2   = 36
r=akar 36
r=6
