∙ 8y agoDiameter: 49/pi = 6.047887837
Radius: 6.047887837/2 = 3.023943919
Area: pi*3.023943919 squared = 28.72746723 square units of measurements

How do you find the circumference of a circle if the area is 49?
You need just a smidgen of algebra.The area of any circle is (pi) x (radius)2 .For this circle, you know that (pi) x (radius)2 = 49.You can massgae this around to find the radius, and thenthe circumference is just (2 pi) x (radius).If you need it all in one step, then Circumference= 2 x sqrt(pi x Area) ,but the other way is easier for me, because I don't have to memorizeanother formula. I find deriving easier than memorizing..
