Question

What is the curved surface area of a
cylinder having base radius 5 cm and
height 10 cm? (Tt = 3.14) *​

Answer 1

Answer:

Csa = 2πrh

=2 x 3.14 x 5 x 10

= 3140 cm2

Answer 2

Answer:

C.S.A of cylinder

$= 2\pi \times r \times h$

Step-by-step explanation:

$= 2\pi \times r \times h \\ = 2 \times \frac{22}{7} \times 5 \times 10 \\ = 2 \times \frac{22}{7} \times 50 \\ = \frac{44}{7} \times 50 \\ = \frac{2200}{7} \\ = 314.2857142857$
