What is the cicumference of 153.86 if that's the area?

Answer 1

To find the circumference of a circle when given the area, you can use the formulas for area ( A = \pi r^2 ) and circumference ( C = 2\pi r ). First, solve for the radius ( r ) using the area: ( r = \sqrt{\frac{A}{\pi}} = \sqrt{\frac{153.86}{\pi}} ). Then, plug the radius into the circumference formula: ( C = 2\pi \sqrt{\frac{153.86}{\pi}} ). Calculating this gives a circumference of approximately 44.04 units.
