Question

the height of a cylinder is 18 cm and the perimeter of the base is 44 cm find the area of curved surface​

Answer 1

Step-by-step explanation:

curved surface area with radius r and height h is

Curved surface area=2π rh (1)

As height=h=8cm

Perimeter of base=2πr

44cm=2πr

r=44/2πcm (2)

Put the value of radius from (2) into (1)

Curved surface area=2π(44/2π)8 cm.cm

Curved surface area=352cm^2
