Question

find the volume,CSA and TSA of a right circular cylinder whose height and radius of the base are 20cm and 14cm respectively​

Answer 1

Step-by-step explanation:

Diameter =14 cm

Radius =7 cm

Height =15 cm

So,

TSA of cylinder =2πr(r+h)

=2×

7

22

×7(7+15)

=2×

7

22

×7×22

=968 cm

2

CSA of cylinder =2πrh

=2×

7

22

×7×15

=660 cm

Answer 2

Answer:

radius- 14cm

height- 20cm

CSA - 2πrh

2×22/7×14×20 = 1760cm^2

TSA- 2πrh(r+h)

= 1760× (14+20)

= 1760× 34

=59840 cm^2

volume= πr^2h

= 22/7×14×14×20

= 12320cm^3
