in question 1. apply formula
L. C. A of right circular cylinder = 2πrh
and apply equation :-
=> 88 = 2* 22/7 * r * 14
then to find diameter apply equation D = 2r
in question 2. apply formula
D = 2r to find the radius
then,
T. S. A of right circular cylinder = 2πr(h + r ) to find the total surface area of metal sheet required.
