Answer:
Radius of earth - R
gravity from
core to crust } - g
so, area of earth - πr²
πr² = g ( gravity is constant at crust )
πr²/2 = g/2 ( half of the value of g )
πr²/2 = g/2 ( we got a perimeter ofsemicircle )
so, πr²/2 m from core to crust ...
surface(g/2) = total - from core ..
= πr² - πr²/2
= πr²/2 m .....
sry, my friend this might be correct because it is just a assumption of mine ..:):););)
