tenda berbentuk kerucut mempunyai luas alasnya 154 m2 dan luas selimut nya 550 m2 tentukan volume dari tenda tersebut

*Lalas = 154
πr² = 154
22/7.r² = 154
22r² = 154.7
22r² = 1078
r² = 1078/22
r² = 49
r = √49
r = 7 m
*Lselker = 550
πrs = 550
22/7.7.s = 550
22s = 550
s = 550/22
s = 25 m
*t = √s²-r²
= √25²-7²
=√625-49
=√576
t=24 m
*Vker = 1/3πr²t
= 1/3.22/7.7.7.24
= 1.22.7.8
V= 1232 m³
