The area of the base is 61,600 sq. cm. II. The height of the tank is 1.5 times the radius. III. The circumference of base is 880 cm. A)  Only I and II   B)  Only II and IIIC)         Only I and IllD)         Only II and either I or III

Volume of cylindrical tank $=\pi {{r}^{2}}h$ So, we need radius and height. Radius can be found from either statement I or III and height from statement II.
