question #1 pls

assume stick is vertically inserted Consider a horizontally-positioned right circular cylindrical oil tank of radius r and length h as in the figure. The tanks are used for storage in various locations and are drained and filled periodically. Inventory is taken by placing a long dipstick with quarter-inch marks vertically in the tank, and then measuring the liquid level w. 1 1). If all variables r, h, and w are in inches, use calculus to find a general formula for the volume V of oil in the tank in gallons. liquid level 2). A certain tank with diameter 32 feet and length 7 feet has its oil level measured at 26°4 inches. How many gallons of oil are in this tank to the nearest tenth of a gallon (1 gallon = 231 in?)? W h 3). What is the fluid force on one end of the tank if the weight density of this crude oil is 50 lb/ft??
