Answer 1

Hey dear ☺️☺️❤️


Ur answer is here.......

ANSWER %%%%
%%%%%%%%%%

Moment of inertia of disc at tangent=5/4mr²=I +mr² (by parallel axis theorem)
I=5/4mr²-mr²=1/4mr²
by perpendicular axis theorem
I+I=I°(perpendicular to plane)
1/4mr²+1/4mr²=mr²/2.

Answer 2

moment of inertia of disc at tangent=5/4mr²=I +mr² (by parallel axis theorem)

I=5/4mr²-mr²=1/4mr²

by perpendicular axis theorem

I+I=I°(perpendicular to plane)

1/4mr²+1/4mr²=mr²/2
