The lateral area of a cone is 612 pi the radius is 14.2 what is the slant height

The formula of lateral surface area of cone is

Here r represents radius and l represents the slant heigh .

In the question it is given that, radius, r =14.2

And

Substituting these values in the formula of lateral area of cone, we will get

Now we need to solve for l and for that we need to divide both sides by 14.2 pi, that is

l = 43 (approx )

what’s the question?
