B(x) gives the number of candy bars for boys, G(x) gives the number of candy bars for girls, and T(x) gives the total
number for both groups. Use the graph to answer the question.
-The radius $\mathrm { r }$ of a circle of known area $\mathrm { A }$ is given by $\mathrm { r } = \sqrt { \mathrm { A } / \pi }$ , where $\pi \approx 3.1416$ . Find the radius and circumference of a circle with an area of $48.71 \mathrm { sq } \mathrm { ft }$ . (Round results to two decimal places.)

• A) \(\mathrm { r } = 15.52 \mathrm { ft } , \mathrm { C } = 97.52 \mathrm { ft }\)
• B) \(\mathrm { r } = 3.94 \mathrm { ft } , \mathrm { C } = 24.76 \mathrm { ft }\)
• C) \(\mathrm { r } = 3.94 \mathrm { ft } , \mathrm { C } = 24.76 \mathrm { sq } \mathrm { ft }\)
• D) \(\mathrm { r } = 3.94 \mathrm { ft } , \mathrm { C } = 8.86 \mathrm { ft }\)
