#"549.5 cm"^3#

Water pipe is in the shape of cylinder

#"V" = pi "r"^2 "h" = 3.14 × ("5 cm")^2 × "7 cm" = "549.5 cm"^3#

#175pi \ "cm"^3#

Since the water pipe has a radius and a height, it's safe to assume that the water pipe is in the shape of a cylinder.

The volume of a cylinder is given by:

#V=pir^2h#

#r# is the radius of the cylinder

#h# is the height of the cylinder

And so, the volume is:

#V=pi*(5 \ "cm")^2*7 \ "cm"#

#=pi*25 \ "cm"^2*7 \ "cm"#

#=175pi \ "cm"^3#

#~~549.8 \ "cm"^3#
