Question

The Outer and inner circumferenceof a pipe are 6.6 cm and 4.4 cm respectively. If the volume of the pipe is 1925cu.cm find the length
of the pipe (π =22/7)​

Answer 1

Answer:

2πR=6.6CM

2πr=4.4CM

R=11.55CM

r=7.7CM

V=π$R^{2}$-$r^{2}$h

1925=22/7(11.55^2-7.7^2)h

1925=22/7(133.4-59.3)h

1925=22/7*74.1h

h=1925*7/22*1/74.1

h=8.26cm
