jawabannya apa hari ini di kumpul

dik : r = 7cm
phi = 22/7
V.kerucut = 1232 cm^3
dit : L.s.kerucut......?
V.kerucut =1/3.phi.r^2.t
1232 = 1/3.22/7.7^2.t
1232 = 1/3.22/7.49.t
1232 = 1/3.154.t
1/3.154.t = 1232
1/3.t = 1232/154
1/3.t = 8
t = 1/3:8
t = 3/1 × 8
t = 24 cm
s^2 = r^2 + t^2
s^2 = 7^2 + 24^2
s^2 = 49 + 576
s^2 = 625
s = akar625
s = 25 cm
L.s.kerucut = phi.r.s
= 22/7.7.25
= 550cm^2
