Let radius of cylinder = $$r$$ cm and height = $$h$$ cm Circumference of base = $$2 pi r = 132$$ => $$2 imes frac{22}{7} imes r = 132$$ => $$r = frac{132}{44} imes 7 = 21$$ cm Volume of cylinder = $$pi r^2 h = 13860$$ => $$frac{22}{7} imes (21)^2 imes h = 13860$$ => $$22 imes 3 imes 21 imes h = 13860$$ => $$h = frac{13860}{66 imes 21} = 10$$ $$ herefore$$ Curved surface area of cylinder = $$2 pi r h$$ = $$2 imes frac{22}{7} imes 21 imes 10$$ = $$44 imes 30 = 1320 cm^2$$
