Question
The volume of a conical tent is 1232m3 and
the area of its base is 154m2. Find the width of the canvas required to build the tent. if the length of the canvas is 11 m. type-sscSolution
Given - πr2 = 154m2 R = 154×7/22 = 7m 1/3× πr2h= 1232 m3 h= 1232×3/154 h= 24m now – l2 = r2+h2 =49+576 =625 l = 25m Area of the canvas required to build the tent = πrl Which will equal to the area of the rectangular canvas. 22/7×7×25 = 11×length of the canvas length of the canvas =50m
