Question

inner and outer diameter of a pipe is 24cm and 28cm respectively. length of a pipe is 35 cm. find the volume of pipe
​

Answer 1

Step-by-step explanation:

Inner radius =

2

24

=12cm

Outer radius =

2

28

=14cm

Height = Length of pipe =35cm

Volume of pipe =π(r

−r

)×35cm

3

=110×52cm

=5720cm

Mass of 1cm

3

wood =0.6kg

Mass of 5720cm

3

wood =(5720×0.6)g

=3432g

=3.432kg

Answer 2

Volume= πr²h

c= 24

24/2r= 22/7

44r= 24*7

r= 24*7/44= 12/22= 6*7= 42/11

...

c= 35

35/2r= 22/7

44r= 35*7

r=35*7/44

.....

arey yeh toh..2 radius nikal raha...
