Question

A 14cm long pipe has external and internal radii respectively as 5cm and 3cm find the volume of the pipe

Answer 1

Answer:

Answer is 704 cm³

Step-by-step explanation:

volume for external raddii is πR²h

=22/7 x 5 x 5 x 14 =1100 cm³

volume of pipe is πr²h

and internal radiii is 3

so volume =

22/7 x 3 x 3 x 14

=396cm³

now volume is 1100-396 =704 cm³
