the frustum is made up of metal sheet whose circular bases are covered . the upper and lower circular bases are 25 π cm ² & π cm² . if the height of a frustum is 3cm , then find the surface area of frustum and cost of metal sheet need if it cost Rs 500 per 100 cm ².. Created by 2001roars. Math

Given :-Height of frustum, h = 3 cmBase Area of frustum of one end of radius, r = π cm²Base Area of frustum of other end of radius, R = 25 π cm² .To Find :-Total Surface Area of FrustumCost of metal sheet needed if it cost Rs 500 per 100 cm² .Formula Used :-where,R = radius of upper end of frustumr = radius of lower end of frustumh = height of frustuml = slant height is frustumTSA = Total Surface AreaSolution :-Given that,Height of frustum, h = 3 cmBase Area of frustum of one end of radius, r = π cm²Base Area of frustum of other end of radius, R = 25 π cm² .So, Also, So,Slant height of frustum isHence, Hence, Cost of metal sheet used to make a frustum is Therefore, Cost of metal sheet = Rs 880.Additional Information :- where,R = radius of upper end of frustumr = radius of lower end of frustumh = height of frustuml = slant height is frustumCSA = Curved Surface Area
