Which of the following could be used to calculate the area of the sector in the circle shown?

π(10in)^2 37 over 360
π(10in)37 over 360
π(37in)210 over 360
π(37in)10 over 360

answer:  

\boxed {\frac{1}{5}}  

━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━

solution-

60 *   \frac{1}{5}   = 12

90 * \frac{1}{5} = 18

75 * \frac{1}{5} = 15

━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━

hence, the answer would be \boxed {\frac{1}{5}}
