Answer 2

Curved Surface Area Of Cylinder = 703.36 cm²

Total Surface Area Of Cylinder = 1934.24 cm²

Step-by-step explanation:

GIVEN

Radius = 14 cm

Height = 8 cm

π = 3.14

___________________________

To Find

Curved Surface Area Of Cylinder

Total Surface Area Of Cylinder

___________________________

We know that,

Curved Surface Area Of Cylinder = 2πrh

Total Surface Area Of Cylinder = 2πr ( r + h )

___________________________

Now Let's find the Curved Surface Area Of Cylinder

Curved Surface Area Of Cylinder = 2πrh

Curved Surface Area Of Cylinder = 2 × 3.14 × 14 × 8

Curved Surface Area Of Cylinder = 6.28 × 14 × 8

Curved Surface Area Of Cylinder = 703.36

Curved Surface Area Of Cylinder = 703.36 cm²

___________________________

Now Let's find the Curved Surface Area Of Cylinder

Curved Surface Area Of Cylinder = 2πr ( r + h )

Total Surface Area Of Cylinder = 2 × 3.14 × 14 × ( 14 + 8 )

Total Surface Area Of Cylinder = 6.28 × 14 × 22

Total Surface Area Of Cylinder = 87.92 × 22

Total Surface Area Of Cylinder = 1934.24

Total Surface Area Of Cylinder = 1934.24 cm²
