Question

calculate the c s a of cylinder shaped pillar of diameter 5.5 cm and height is 3.5 CM​

Answer 1

Answer:

curved surface area of cylinder = 2π r h

= 2 * 22 / 7 * 2.25 * 3.5

= 2 * 22 / 7 * 225 / 100 * 35 / 10

= 49.5 cm^2

hope it helpful

Answer 2

Answer:

60.5 cm²

Step-by-step explanation:

Diameter = 5.5cm

Radius = 5.5/2 = 55/20cm

Height = 3.5 = 35/10cm

C.S.A. of Cylinder:

>> 2 π r h

>> 2 * 22/7 * 55/20 * 35/10

>> 22 * 55 /20

>> 11 * 55 /10

>> 605/10

>> 60.5 cm²
