The answer is b I think that is the answer
Answer:
The options are unclear but the answer is 8^2π square feet or 64π sqfeet
Explanation:
Area of a circle is denoted by: πr^2 where r is the radius of the circle.
In this question, the diameter was given. The diameter of a circle is twice the radius. Therefore, in order to get the radius, we divide the diameter by 2 i.e. r = d/2
= 16/2 = 8 feet.
Thus, the radius = 8 feet.
Hence, Area of a circle = πr^2
= π × 8^2
= 64π or 8^2π sqfeet.
Answer:
By 1900, Fingerprint was the evidence which was collected at crime scenes to help positively identify suspects by one particularly unique trait. No two people can have the same type of fingerprints. It is a unique characteristic which is even not common among identical twins. Therefore, was considered as an important evidence for identification of suspects and linking them with the scene of offence. In 1904, the city of St.Louis, Missouri used fingerprint evidence for the first time for criminal identification.
