Acylinder has a volume of 245 cubic units and a height of 5 units. the diameter of the cylinder is 7 units 14 units 49 units

The diameter is twice that, or approx. 7.90 units.

Step-by-step explanation:

the equation for the volume of a cylinder of radius r and height h is

V = πr²h.  Here we need to calculate the diameter after having found the radius.  Solving V = πr²h for r², we get:

           V

r² =

         πh

Substituting the given values, we obtain for r² the following:

         145 units³

r² =  = 15.6 units²

       3.14159(5 units)

Taking the square root of both sides, we get:

r = √15.60, or approx. 3.95 units.

The diameter is twice that, or approx. 7.90 units.

found it xd it ok yt

let m = monomial

let t = trinomial

so, m times t = t.

monomial times a trinomial = another trinomial.
