You can if you want to. The answer will always be (2 pi) x (radius)2 . I don't know how that would be helpful.
I am not sure that it is particularly helpful!
In some ways, yes.

What is 43 inches? The Area? The circumference? The Diameter? If the diameter is 43 inches than the radius is 21.5 inches If the Circumference is 43 inches than the radius is 6.96 inches If the Area is 43 inches than the radius is 3.7 inches Hope this is helpful :)

You measure circumference by multiplying the diameter by pi. If it gives you the radius, multiply the radius by 2 to get the diameter then multiply it by pi. Here are some helpful formulas: Area: A=Pi r2 Diameter (If given radius) D= r x 2 Radius (If given diameter) R=d/2 Circumference= d x pi See the related link for a helpful website to look through if you need anything else.
Well it can be helpful in many ways for example in find cheaper solutions for gathering energy,growing food etc.
