open cylindrical tank of radius 14 m and height 3 m is made from a sheet of metal. How much sheet of metal is required ? Also find the cost of sheet @ * 100 per m².
= height of sheet of metal = 3 metre
= breadth of sheet of meter = circumference of the cylinder = 2 pi r = 44/7 * 14 = 44 *2 = 88 meter
= area of sheet of metal required is equal to L*B = 3*88 = 264 square meter
= cost of sheet at 100 per m².= 264 * 100 = 26400 rupees
