any help is greatly appreciated !

V The radius of a cylindrical water tank is 5.5 , and its height is 10 ft- 5.5 ft Answer the parts below. Make sure that you use the correct x- units in your answers. If necessary, refer to the 10 list of geometry formulas. (a) Find the exact volume of the tank. Write your answer in terms of 7:. Exact volume: [I] (b) Using the ALEKS calculator, approximate the volume of the tank. To do the approximation, use your answer to part (a) and the 1: button on the calculator. Round your answer to the nearest hundredth. Approximate volume: I] V Consider a sphere with a radius of 7.1 cm. Using the ALEKS calculator, approximate the volume of the sphere. To do the approximation, do not round any intermediate steps, and use the 1: button on the calculator. Round your answer to the nearest hundredth. If necessary, refer to the list of geometry formulas. Make sure that you use the correct units in your answer. Approximate volume: I] V Consider a cone with a height of 15 m and a base radius of 6 m. Using the ALEKS calculator, approximate the volume of the cone. To do the approximation, do not round any intermediate steps, and use the it button on the calculator. Round your answer to the nearest hundredth. If necessary, refer to the list of geometry formulas. Make sure that you use the correct units in your answer. Approximate volume: [I
