Question

The curved surface area of a cylinder is 1100 cm square and its diameter is 20 cm find its height .

Answer 1

curved surface area of a cylinder = 2 * pi * r * h = 1100 »●

r is radius

h is height of cylinder

given diameter = 10 = 2* radius

radius = 10/2 = 5 cm

pi is a constant ~ 3.14

By substituting all values in ●

2 * 3.14 * 5 * h = 1100

h ~ 35.01 cm

Hope you understand

if you have any doubts, comment ;)(

Answer 2

Answer:

given=10=2radius

radius=10/2=5cm

pi is a constant 3.14

2×3.14×5×h=1100

h= 35.01 cm
