Question

If the radius of cylinder is 7 cm and height is 14 cm find its curved surface area , total surface area and volume​

Answer 1

Answer:

curved surface area : 616cm^2

total surface area : 4312cm^2

volume : 2156

Answer 2

Answer:

CSA = 616 cm sq.

TSA = 322 cm sq.

VOL = 2156 cubic cm

Step-by-step explanation:

A cylinder has ,

radius = 7 cm

height = 14 cm

curved surface area (CSA ) = 2πrh

= 2 × 22/7 × 7 × 14

= 616 cm sq.

Total surface area (TSA) = 2πr ( r + h )

= 2 × 22/7 × 7 ( 7 + 14 )

= 322 cm sq.

volume (V) = πr^2 h

= 22/7 × 7 ×7 × 14

= 2156 cm cube
