Step-by-step explanation:
Base Area = 616 = pi r square
Height = 30 cm
Volume = Base area * height
= 616 * 30 = 18480 cm cube
TSA of cylinder = 2 *pi*r*h +@2*pi*r square
We now ,
pi*r square = 616
hence, r square = 616 ÷ pi
hence r square = 616×7÷22 = 196
hence, r = root196 = 14
TSA = 2*22÷7 * 14*30 + 2(616)
=2640 + 1232 = 3872 cm square
