Q8 of 107 Page 17

A circus tent has cylindrical shape surmounted by a conical roof. The radius of the cylindrical base is 20 m. The heights of the cylindrical and conical portions are 4.2 m and 2.1 m respectively. Find the volume of the tent.

Given radius of Cylindrical base = 20 m


Height of Cylindrical part (h) = 4.2


Volume of Cylindrical = ….(1)


V1 =π(20)2 4.2


= 5280 m3


Volume 0f Cone =


Height of conical part (h) = 2.1 m …..(2)


V2 (20)2 (2.1)


= 880 m3


Volume of tent (v) = V1 + V2


V = 5280 + 880


= 6160 m3

A toy is in the shape of a right circular cylinder with a hemisphere on one end and a cone on the other. The radius and height of the cylindrical part are 5 cm and 13 cm respectively. The radii of the hemispherical and conical parts are the same as that of the cylindrical part. Find the surface area of the toy if the total height of the toy is 30 cm.

A cylindrical tub of radius 5 cm and length 9.8 cm is full of water. A solid in the form of a right circular cone mounted on a hemisphere is immersed in the tub. If the radius of the hemisphere is immersed in the tub. If the radius of the hemi-sphere is 3.5 cm and height of the cone outside the hemisphere is 5 cm, find the volume of the water left into hr tub.
