Class-9:Surface Areas and Volumes of right circular cone #how to find T.S.A.,C.S.A & Volume of Cone #Formula for total Surface area of Cone #how to find curved Surface area of Cone #how to find volume of Cone #Formula.for volume of a Cone #length of circular edge of Cone #the radius and slant height of a Cone are in the ratio of 4:7.If it's curved Surface area is 792sq.cm.find it's radius. #A joker's cap is in the form of right circular cone of base radius 7cm and height 24cm,find the cost of sheet required to make 100 such caps if 1sq.m of sheet used for making cap costs ₹700. #A conical tent is to accommodate 11 persons.Each person should have 4sq.m.of space on the ground and 20cubic metro of air to breathe.find the height of the Cone. #A slant height and base diameter of a conical tomb are 25m and 14m,respectively. Find the cost of white-washing it's curved Surface at the rate of ₹210 per 100sq.m. #find the Volume of the largest circular cone that can be cut out of a cube whose edge is 10cm. #there are two cones .the curved Surface area of one cone is twice that of the other.the slant height of the later is twice that of the former.find the ratio of the radii. #mensurationclass9th #mensurationtricks #mensurationmaths #mensuration #ncertmaths9th #mathematicsclass9 #mathstricks #maths_withvarsha #mathshorts #ytviralvideo
