Question

curved surface area of cylinder
100 cm. Find its height
if
radius of cylinder
the
is 2 cm​

Answer 1

Answer:

Given :

curved surface area = 100

radius =2

formula:

curved surface area = 2πrh

100 = 2 × 22/7 × 2 × h

100 = 44/7 × 2 × h

100 = 88/7 × h

100 × 7 / 88 = h

700 /88 = h

h = 7.954..

h ≈ 8 cm
