Question

The height of a cylinder is 10cm and its curved surface area is 880 cm2. Find the diameter of the cylinder.
​

Answer 1

Answer:

diameter = 28 cm.......

Answer 2

Step-by-step explanation:

Curved Surface Area of a cylinder = 880 cm2

Height = 10cm

Curved Surface Area of a cylinder = 2πrh

880cm^2 = 2 x 22/7 x r x 10cm

880cm^2 = 440/7r

880cm^2 x 7/440 = r

2 x 7 = r

14cm = r

D = r x 2

D = 14cm x 2

D = 28 cm
