Answer 1

Given-

Circumference of base, 2πr = 44 cm

Height of cylinder, h = 15 cm

To find-

Curved surface area, CSA

Solution-

Curved surface area of cylinder

= 2πrh

= 2πr× h

= 44 × 15

= 44 ×5 × 3

= 220× 3

= 660 cm²

Option (b)

Answer 2

Answer:

B is correct.

given

$2\pi \: r = 44cm$

CSA of cylinder=

$2\pi \: r \: h$

h=15cm

so total 15*44=660cm2
