Iam failing and it is a very important testthe circumference of a circle is 16π inches. show how you can use this information to calculate the same circle’s area.

Circumference=2*pi*r or pi*d so if its 16pi you know that your diameter is 16 wich means your radius is 8 because d/2 is your radius. plug the 8 into the area formula wich gives you the formula pi*8^2. 8squared is 64. 64 times pi is 201. or 64pi wich is the area of the same circle with the circumfernce of 16pi

The answer is: y would equal 3 because if you simplify the equation then it would be y= 3x+9 and if you divide 3x and 9 by 3 it would equal 3. y= 3
