hmm
BCUZ TSA [total surface area] OF CYLINDER IS 2pi r (r+h)
oh sorry
is it
right
its fine... everyone makes mistakes you dont need to be sorry..
check my answer now is it correct?
hey mallu, what is your problem? no more comments please
is my answer correct?
how have you got the measurements, there not a single number is given?

Let the radius be 'r'
So, height=r
So, total surface area=2*(22/7)*r*r+2*(22/7)*r^2
= 44r^2/7+44r^2/7
= (44r^2+44r^2)/7
= 88r^2/7
So, the total surface area = 88r^2/7
[total surface area of cylinder=2*(22/7)*r*h+2*(22/7)*r^2]
