Question

Find the curved surface area and total surface area of the cylinder (radius:35 cm, height:10.5 cm)

Answer 1

Answer:

Given:

• Radius of Cylinder = 35cm

Height of Cylinder = 10.5cm

To Find:

It's Curved Surface Area and Total Surface Area

Formula Used:

CSA of Cylinder = 2πrh

TSA of Cylinder = 2πr(h+r)

Solution:

Firstly,

:⇒ CSA of Cylinder = 2πrh

2 X 22 7 CSA of Cylinder x 35 x 10.5

CSA of Cylinder

2 x 22 x 5 x 10.5

CSA of Cylinder = 2,310 cm²

And,

: TSA of Cylinder = 2πr(h+r)

:

TSA of Cylinder

22

7

=

2 x

x 35(10.5 + 3

TSA of Cylinder = 2 x 22 × 5 × 40.5

: TSA of box = 8, 910 cm²

Hence, The Curved Surface Area of Cylinder is 2,310cm² and Total Surface Area of Cylinder is 8,910cm².
