If r = 5 units and x = 11 units, then what is the volume of the cylinder shown above? (I could not add the picture)
A.
275 cubic units
B.
55 cubic units
C.
160 cubic units
D.
1,100 cubic units

the answer is A

Step-by-step explanation:

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
