Half a sphere, which is a 3D shape, is called a hemisphere.
The semi-circles in the question is a 2D shape and will make a circle.
2, because semi means half.
The circle's diameter
It makes a sphere
I know one of them is a circle
The radius is half the diameter.
2, because semi means half.
The circle's diameter
It is certainly possible to draw a 2 dimensional picture of a sphere, and make it look like a true sphere.
school
The diameter in the line through the circle that defines the 2 semicircles created.
It makes a sphere
I know one of them is a circle
Its diameter
yes * * * * * No, they do not tessellate.
The radius is half the diameter.
1. cut the cake in half horizontally so it has 2 tiers (2 circular cakes sitting on top of each other) 2. cut the cake in half vertically so you have 2 semicircles on each layer 3 cut the 2 semicircles in half so you have 2 tiers each cut into 4 pieces.
None. It is not possible to make a sphere in that fashion.
