Question

The shape of an ice-cream cone is a combination of:
(a)Sphere+cylinder
(b)Sphere+cone
(c)Hemisphere+cylinder
(d)Hemisphere+cone

If a cone is cut parallel to the base of it by a plane in two parts, then the shape of the top of the cone will be a:
(a)Sphere
(b)Cube
(c)Cone itself
(d)Cylinder

If we cut a cone in two parts by a plane parallel to the base, then the bottom part left over is the:
(a)Cone
(b)Frustum of cone
(c)Sphere
(d)Cylinder

If r is the radius of the sphere, then the surface area of the sphere is given by;
(a)4 π r2
(b)2 π r2
(c)π r2
(d)4/3 π r2

If we change the shape of an object from a sphere to a cylinder, then the volume of cylinder will
(a)Increase
(b)Decrease
(c)Remains unchanged
(d)Doubles

Fifteen solid spheres are made by melting a solid metallic cone of base diameter 2cm and height 15cm. The radius of each sphere is:
(a)½
(b)¼
(c)1/3√2
(d)1/3√4

The radius of the top and bottom of a bucket of slant height 35 cm are 25 cm and 8cm. The curved surface of the bucket is:

(a)4000 sq.cm
(b)3500 sq.cm
(c)3630 sq..cm
(d)3750 sq.cm

If a cylinder is covered by two hemispheres shaped lid of equal shape, then the total curved surface area of the new object will be
(a)4πrh+2πr2
(b)4πrh-2πr2
(c)2πrh+4πr2
(d)2πrh+4π2

A tank is made of the shape of a cylinder with a hemispherical depression at one end. The height of the cylinder is 1.45 m and radius is 30cm. The total surface area of the tank is:
(a)30m
(b)3.3m
(c)30.3m
(d)3300m

If we join two hemispheres of same radius along their bases, then we get a;
(a)Cone
(b)Cylinder
(c)Sphere
(d)Cuboid
