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 then
the 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 memorize
another formula. I find deriving easier than memorizing..
What else can I help you with?

What is the diameter of a circle with a circumference of 49 centimeters?
Oh, dude, math time! So, the formula for finding the diameter of a circle from the circumference is dividing the circumference by π (pi). In this case, 49 divided by π is approximately 15.57 centimeters. So, the diameter of the circle is around 15.57 centimeters. Easy peasy, right?

What is the circumference of a circle with a radius of 7.8 meters?
Circumference of circle: 2*pi*7.8 = 49 meters rounded
What is the circumference of a 49 inch circle?
The circumference of a circle is calculated using the formula C = 2πr, where C is the circumference, π is the mathematical constant pi (approximately 3.14159), and r is the radius of the circle. In this case, since the diameter of the circle is given as 49 inches, the radius would be half of the diameter, which is 24.5 inches. Plugging this value into the formula, the circumference of the 49-inch circle would be approximately 154.06 inches.
