Answer:
1/6
Explanation:
The circumference of a circle is denoted by: C = 2πr, where r is the radius. Here, we see that the radius is 1, so plug this in:
C = 2πr
C = 2π * 1 = 2π
We see that arc AB has length π/3, so to find the fraction of the circumference this is, divide π/3 by 2π:
(π/3) ÷ 2π = (π/3) * (1/2π) = 1/6
Thus, the answer is 1/6.
Relative Dating; One fossil is found to be older than another fossil.
Absolute Dating; Age of a fossil is found to be 61.1 million years old.
<h3>How to classify fossils?</h3>
Relative dating is defined as the age of a rock layer (or the fossils it contains) compared to other layers. This dating can be gotten by looking at the position of rock layers. Whereas, absolute dating is the numeric age(specific age) of a layer of rocks or fossils. Absolute age can be determined by using radiometric dating.
1. Relative Dating; One fossil is found to be older than another fossil.
This is because In an excavation of a project area, if we see a set of fossils found 5 meters down, they will be younger than fossils found 17 meters down.
2. Absolute Dating; Age of a fossil is found to be 61.1 million years old.
A fossil analyzed with radiometric dating would have undergone maybe 2 half lives of radioactive isotope.

<h3>What is the distinction among Jurassic and Cretaceous?</h3>
The Jurassic duration, from approximately two hundred million to a hundred forty five million years in the past, ushered in birds and mammals. And the Cretaceous duration, from a hundred forty five million to sixty six million years in the past is thought for its iconic dinosaurs, together with Triceratops, and pterosaurs together with Pteranodon.
The Cretaceous ( /krəˈteɪʃəs/ krə-TAY-shəs) is a geological duration that lasted from approximately a hundred forty-five to sixty six million years in the past (Mya). It is the 1/3 and very last duration of the Mesozoic Era, in addition to the longest.
