The volumes of 2 similar solid cones are 1080 cubic centimeters and 1715 cubic centimeters. If the curved surface area of the smaller cone is 840 square centimeters, find the curved surface area of the larger cone.

L.S.F2=A.S.F
L.S.F3=V.S.F
V.S.F
V.S.F=vol. of large cone/vol. of small cone
V.S.F=1715cm3/1080cm3
=1.588(4sf)
L.S.F=3v(1.588)
=I.167(4SF)
