Question

the radius and height of a cylinder are 2 and 4 then __ is its curved surface area​

Answer 1

Step-by-step explanation:

radius = 2

height=4

curved surface area = 2πrh

=2π×2×4

=16×22/7

=50.287

≈ 50.29unit²

Answer 2

Step-by-step explanation:

r=2 ;h=4

curved surface area of cylinder=2πrh

=2x3.14x2x4

=16x3.14

=50.24sq.unit(approx)
