If the circumference of a circle is increased by 50 then the area will be increased by?

there is no constant that will calculate this, since circumference is calculated with only radius and area with radius squared. you will have to calculate the radius using the initial circumference and then the radius again for the new circumference (with the 50 added). then calculate an area for each radius..then you can see the increase.
