Find the diameter of a cylindrical construction pipe is 4 ft. If the pipe is 18 ft. Long, what is its volume? Use the value 3.14 and round your answer to the nearest whole number

395 .64 ft2

Step-by-step explanation:

hmm, let's see :

Pi = 3.14 r = 3 ft h = 14 ft

Volume = 3.14 * (3)2 ft *14 ft= 395 .64 ft2

— hope this helped :)! (sorry if there is any mistake !!)

the direct variation says that:

then the equation is of the form is given by:

            where k is the constant variation.

from the given table:

consider any value of x and m(x)=y

x = 2 and m(x)=y = 3

substitute these value in [1]; we have;

divide both sides by 2 we get;

⇒

check:

put x = -1 and m(x) = -1.5

substitute in the equation:

-1.5 = -1.5                   true

therefore, the function m(x) represents a direct variation
