Answer:
this is a no solution problem, nothing could sub for x and make this true
Answer:
Yes you are on the right track!
Step-by-step explanation:
L x w x h = volume
volume = 5 x 5 x 5 = 125 cm ^ 3
Using the cube formula for volume I got V=3.38cm^3
Answer:
the volume of the pipe is 649.98 cubic inches.
Step-by-step explanation:
We have been given that a collar of Styrofoam is made to insulate a pipe. We are asked to find the volume of the given pipe.
We will use volume of hollow cylinder formula to solve our given problem.

where,
R = Radius of external cylinder,
r = Radius of internal cylinder.
h = Height of cylinder.
substituting our given values in above formula, we will get:

Therefore, the volume of the pipe is 649.98 cubic inches.
