it is given that,CSA of solid right circular cylinder is 2200 m2andcircumference at the base of cylinder is 110 m.we are asked to find height and radius.so,circumference of cylinder = 2*pie*r110 m = 2*22/7*r= 44*r / 7r = 44 / 7*110r = 44 / 770r = 17.5 now ,CSA of cylinder = 2*pie*r*hwe know 2*pie*r = 110 mso ,CSA = 110*h2200 m2= 110*hh = 2200 / 110h = 20 THEREFORE,height = 20 mradius = 17.5 m
