Question

if the cylindrical diameter and height are 14cm and 7 CM respectively, find the curved surface area
​

Answer 1

Answer:

curved surface area of cylinder= 2 pir h

= 2 × 22/7 × 7 × 14

=44 × 14

=616 cm^2

Answer 2

Step-by-step explanation:

r = d/2

r = 14/2 = 7cm

h = 7cm

CSA of cylinder = 2πrh

". = 2*22/7*7*7

". = 2*22*7 = 44*7 = 308cm^2
