Any circle drawn around the Earth divides it into two equal halves called hemispheres. There are generally considered to be four hemispheres: Northern, Southern, Eastern, and Western.

1 Answer. There is no difference when describing a shape. The origin of ‘Hemi’ is Greek, meaning half and ‘Semi’ is Latin. I have never heard anyone using the word semisphere.

A hemisphere is a three-dimensional shape that is half of the sphere. When a sphere is cut by a plane passing through its center, the shape we get is called the hemisphere. A hemisphere has a curved surface and one flat circular base.

A hemisphere is a half-sphere, for example, half the Earth: northern, southern, eastern, western hemisphere.

The height of the sphere is h = 2r. The radius of the cylinder is r. The height of the cylinder is h = 2r….

The volume of a sphere is the amount of space that is inside the sphere. Thus, the volume of a quarter sphere is one-fourth of the volume of a full sphere.

1 : one of the halves of the earth as divided by the equator or by a meridian. 2 : a half of a sphere. 3 : either the left or the right half of the cerebrum.

Therefore, the volume of a hemisphere formula is as follows: V = V(sphere)/2 , V = 2/3 * π * r³ .

The formula for the volume of a sphere is V = 4/3 πr³.

Volume of a sphere = 4/3 πr3 The difference between the two shapes is that a circle is a two-dimensional shape and sphere is a three-dimensional shape which is the reason that we can measure Volume and area of a Sphere.

The surface area of a sphere is defined as the region covered by its outer surface in three-dimensional space. A Sphere is a three-dimensional solid having a round shape, just like a circle. The formula of total surface area of a sphere in terms of pi (π) is given by: Surface area = 4 π r2 square units.

Surface area (TSA) = CSA = 4πr2. Hemisphere : Curved surface area(CSA) = 2 π r2. Total surface area = TSA = 3 π r2.

LSA or lateral surface area is the areas of the lateral surfaces of an object. CSA or curved surface area is the area of the curved surfaces of an object. CSA of cylinder or hemisphere are the same as their LSA.

The curved surface area of a cylinder is defined as the area of its curved surface or the area obtained after excluding the area of its two circular bases. The CSA of cylinder having its base radius ‘r’ and height ‘h’ is given by: Curved surface area (CSA) of cylinder = 2πrh sq. units.

Answer. 512 balls can be made. Let, n ball of each radius 1 cm could be made from the ‘solid sphere’. Hence 512 balls of radius 1 cm can be made from a “solid sphere of radius 8 cm”.

512 numbers

512 balls

Complete step-by-step answer: Hence, the number of balls of radius 1 cm that can be made from a solid sphere of radius 4 cm is 64.

Two small spheres

=64 balls.

64 balls

Hence the number of balls with given radius 1cm that can be made out of the solid sphere of lead with given radius 8cm ] is 512.

Solution. So, the number of lead shots that can be made from the cuboid is 84000.

Required number of balls = 64 .

15.27 spherical balls can be fitted inside the given cubical box. OR 15 complete spherical balls can be fitted inside the given cubical box.

Total number of balls in this case = (108+88) = 196.

Hence, number of balls made =34π×2334π×83=64. Was this answer helpful?

Therefore, the number of lead shots are 84000.

Answer: The number of lead shots obtained from the cuboids are 84076 .

We know that each lead shot is in the shape of a sphere. The volume of a sphere is given by the formula 43πr3, where r is the radius of the sphere. Now, we will find the number of lead shots that can be made using the cuboid. The volume of lead in the cuboid is used to make the lead shots.
