curved surface area of right circular cone is 10010 sq cm, radius=35, what is it volume?

volume of cone=1/3*πr^2h given r=35 curved surface area=πrl=10010 r value substitute in c.s.a,we get l then l=√h^2+r^2 substitute r and l values in above we get h value. finally we get h,r values these values substitute in volume of the cone
