πr²h=150π,
then
r²×6=150,
r²=150/6,
r²=25,
then
r=5 cm,
therefore
C.S.A of the cylinder=2πrh,
=2×π×5×6=60π cm²,
now T.S.A of the cylinder=2πr(h+r),
=2π×5(6+5),
=10π×11,
=110π cm²
then
r²×6=150,
r²=150/6,
r²=25,
then
r=5 cm,
therefore
C.S.A of the cylinder=2πrh,
=2×π×5×6=60π cm²,
now T.S.A of the cylinder=2πr(h+r),
=2π×5(6+5),
=10π×11,
=110π cm²
