We won't solve questions for you.
Show what you tried, we can discuss.

Sorry didn’t know that

Can you tell how to solve the Q6 &7 ?

[exotic wing]

(6) Consider the cone as a surface of revolution made by a line segment (so, a linear function).
(7) There are several approaches. For example, take the function y = √(R^2 - x^2) and inscribe a rectangle in it like this. Find its area, then optimize.

Thanks a lot

Any corrections/ comments for this ?

[exotic wing]

That's incorrect.
While you had a right idea about logarithmic differentiation, you need to apply it for each term separately.

After all, log(a + b) isn't equal to log(a) + log(b).

[frank timber]

Thanks for the correction

Appreciate it
