The volume of a box(V) varies directly with its length(l). Using k for the constant of proportionality, express the relationship between V and l if V varies directly with l.

V = L (k)

Step-by-step explanation:

Hi, to answer this question we have to write an equation with the information given:

We know that the volume of the box (V) varies directly with its length (l).

So, the expression for the volume is:

V = L (k)

What is the area of a circle with a radius of 6 inches?

We know,

Radius = 6 inches (Given)

So, Area of circle = π(6)² = 36π in²

The area of a circle with a radius of 6 inches is 36π in².

Hence, option (c) 36π in² is correct. [Answer]
