A New Chocolate Company Is Estimating How Many Candy Bars $\mathrm { r }$

A new chocolate company is estimating how many candy bars per week college students will consume of their line of
products. The graph shows the probable number of candy bars students (age 18-22) will consume from year 0 to year 10.
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
-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 $45.17 \mathrm { sq } \mathrm { ft }$ . (Round results to two decimal places.)

A) $\mathrm { r } = 3.79 \mathrm { ft } , \mathrm { C } = 8.86 \mathrm { ft }$
B) $\mathrm { r } = 14.36 \mathrm { ft } , \mathrm { C } = 90.23 \mathrm { ft }$
C) $r = 3.79 \mathrm { ft } , \mathrm { C } = 23.81 \mathrm { sq } \mathrm { ft }$
D) $\mathrm { r } = 3.79 \mathrm { ft } , \mathrm { C } = 23.81 \mathrm { ft }$
