By mechanically or ( by the state of liquids) ,
The Earth is divided into different spheres , i.e. , the lithosphere, asthenosphere, mesospheric mantle, outer core, and the inner core.( which is based on physical properties )
Answer:
C. 2π cm
Explanation:
Measure of the length of arc(QR) = θ/360 × 2πr
Where,
θ = 60°
r = 6 cm
Plug in the values
Measure of the length of arc(QR) = 60/360 × 2 × π × 6
= 1/6 × 12 × π
= 2 × π
= 2π cm
The age of the Earth is around 4.6 billion years old
