Question

Find The Surface Area Of The Cylender Please

Answer 1

Answer:

CSA of cylinder = 2 pi r h = 2 × 3.14 × 3 × 12 = 226.08 cm^2

TSA = 2 pi r^2 + 2 pi r h = 2×3.14×9 + 226.08 = 56.52 + 226.08 = 282.6 cm^2

Answer 2

Answer:

hey .!

r =6/2 =3 cm

area = curved surface area+ area of two faces

=2πr.l + 2×(πr²)

= 2πr ( l+ r)

=2×3.14 (12+3)

=2×3.14×15

=30×3.14

= 942.0 cm² ( ans.)
