Hi, for quesion 2 a ii. The question asks you to prove the that T is independant of V.

The proof in the book uses D to - 2 (pie) r Which makes sense cos thas the circumference right?

But the mark scheme sues D as r.

I dont understand how they get the answer. Can someone please explain...Thanks.


Can u post the question so it is easier to follow plz?
