base area of cone=616 sq.cm.
πr^2=616
22/7xr^2=616
r^2=616x7/22
r^2=196
r =√196
r =14
height=48cm
l^2=h2+r^2
l=√48^2+14^2
l=√2304+196
l=√2500
l=50cm
T.S.A of cone =πr(r+l)
=22/7x14(14+50)
=2816cm^2
hope it hlps u

is am correct
no you are not correct
i will edit my ans
because you written the formulae of total surface area of cone is wrong
ok
it is 2pier(r+h)
ok
ok
