(C) Given,the area of the circle $A = 75.46\, cm^{2}$.We know that the area of a circle is given by the formula $A = \pi r^{2}$.Taking $\pi = 3.14$,we have $75.46 = 3.14 	imes r^{2}$.$r^{2} = \frac{75.46}{3.14} = 24.0318... \approx 24.01$.Taking the square root,$r = \sqrt{24.01} = 4.9\, cm$.The circumference of the circle is given by $C = 2\pi r$.$C = 2 	imes 3.14 	imes 4.9 = 6.28 	imes 4.9 = 30.772\, cm$.Rounding to one decimal place,the circumference is $30.8\, cm$.
