• attend is in the shape of light circular cylinder up to height of 3 m and colinical above the total height of the tent is 13.5 5 m and radius of its 14 m find the cost of clouds required to make the 10th at the rate of per square metre
• what is cone surface area
• A rocket is in the form of circular closed at the ler end and a cone of same radius is attached to the top.The radius of the clylinder is 2.5m ,it's height is 21m and the slant height of the cone is 8m Find the T.S.A of rocket
• a wooden toy rocket is in the shape of cone mounted on a cylinder. The height of the entire rocket is 15 cm, while the height of the conical part is 4 cm. The base of the conical portion has a diameter of 6 cm, while the base diameter of the cylindrical portion is 4 cm. If the conicle portion is painted green and the cylindrical portion is painted blue, find the area of the rocket. (use ?=3.14)
• 8th one
  
• A hemispherical  depression  is  cut  out  from  one  face  of  cubical  block  of  side  7cm,  such  that                   the  diameter  of  the  hemisphere  is  equal  to  the  edge  of  the  cube.  Find  the  surface  area  of  the remaining  of  solid. .
• In cuboid the length of its diagonal is 5√5 and sum of its length breadth and depth is 19 than find it's TSA
• Why isn't the base of the cylinder included in the TSA of the bird bath??
  
• a tent is in the shape of a right circular cylinder up to a height of 3 m and conical above it. the total height of the tent is 13.5 m and the radius of its base is 14m. find the cost of cloth required to make the tent at the rate of rs. 80 per metre.   
• Acircus tent is cylindrical upto a height of 3.3m and conical above it. If the slant height and perpendicular height of conical part is 40 m and 24m respectively, then find the total canvas used in making a tent. Also find the cost of canvasing a tent at the rate of rs.12.5 per m sq. (II=3.14)
