Question

circumference of the base of the cylinder is 44cm and it's height is 10cm then the curved surface area of the cylinder is????????????​

Answer 1

• The Curved Surface Area of Cylinder is 440 cm².

Step-by-step explanation:

Given:-

• Circumference of the base = 44 cm.

• Height of Cylinder = 10 cm

To Find:-

• It's Curved Surface Area

Formula used:-

• CSA of Cylinder = 2πrh

• Circumference of circle = 2πr

Solution:-

Firstly,

Circumference of circle $= 2πr$

$44= 2×\dfrac{22}{7}×r$

$r= \dfrac{44×7}{22×2}$

$r= 7$

Now,

CSA of Cylinder $= 2πrh$

$=2×\dfrac{22}{7}×7×10$

$=2×22×10$

$=440\:cm²$

Hence, The Curved Surface Area of given Cylinder is 440 cm².
