The ceramic bowl is 396,000 years older than the other artifact.
Age of ceramic bowl = 400,000
Other artifact = 1/100 times the age of ceramic bowl
Therefore, the age of the other artifact will be :
400,000 × (1/100) = 4000 years
The difference between the age of the ceramic bowl and the other artifact :
Age of ceramic bowl - age of other artifact
400000 - 4000 = 396,000
Hence, the ceramic bowl is 396,000 years older than the other artifact.

Answer:
diameter=twice of radius or d=2r
and radius is half the diameter or r=d/2.
Step-by-step explanation:
As you know circle is a figure whose all points are equidistant from a fixed point or center point. the distant b/w center point and any point on the circle is called radius. and the line which passes through the center of circle and touches far both of center is called diameter.
mathematically you can understand in this way
diameter=twice of radius or d=2r
and radius is half the diameter or r=d/2.
