Question

The volume of a right circular cylinder pipe is 550 cubic cm. lf the diameter of pipe is 1 cm, then find the length of the pipe.

Answer 1

From the question we have a right cylindrical pipe
Volume of the given cylinder is 550cm3
Diameter of the base of the cylinder =1cm
→radius of the cylinder (r) =1/2cm =0.5cm
Let the lengthy of the given pipe be h cm.

So , according to question we have
22/7×(0.5)^2 ×h =550
22/7×0.25 ×h =550
550/700h =550
h =700
Thus, the required length of pipe =700cm
=7m
