Let the height of the cone be h.
Volume of cone = 9856 cm3
h = 48 cm
Therefore, the height of the cone is 48 cm.
(ii) Slant height (l) of cone 
Therefore, the slant height of the cone is 50 cm.
(iii) CSA of cone = πrl
= 2200 cm2

(i)V = 1/3 * π* r*r*h
9856 = 1/3 *(22/7) *14*14*h
h= (9856*3*7)/(22*14*14)
=48 cm
(ii) slant height
l = √(r*r + h*h) = √ (196+2304)
= √2500 = 50 cm
(iii) curved surface area
π*r*l = (22/7)*14*50
=2200 cm^2
