Question

find the curved surface area of a cylinder whose radius is 7 cm and height is 7 cm​

Answer 1

Answer:

308 cm²

Step-by-step explanation:

CSA of cylinder =2πrh

Given r=7 cm, h = 7cm

Substituting π=22/7, we get

2πrh = 2×22/7×7×7

=》 44×7

=》 308 cm²

Answer 2

Given:-

• Radius of Cylinder = 7 cm

• Height of Cylinder = 7 cm

To Find:-

• Curved Surface Area of Cylinder

Formula used:-

• CSA of Cylinder = $2πrh$

Solution:-

CSA of Cylinder = $2πrh$

CSA of Cylinder = $2×\dfrac{22}{7}×7×7$

CSA of Cylinder = $2×22×7$

CSA of Cylinder = $308\:cm²$

Hence, the Curved Surface Area of Cylinder is 308 cm².

• Total Surface Area = $2πr(h + r)$

• Area of two base = $2πr²$

• Volume = $\dfrac{1}{3}πr²h$
