A) \[3\frac{3}{11}m\]
B) \[5\frac{6}{11}m\]
C) \[6\frac{6}{11}m\]
D) \[6\frac{2}{11}m\]
Correct Answer: A
Solution :
Let the radius of the semicircle be x m. According to the question, \[\pi r+2r=\pi {{r}^{2}}=\pi +2=\pi \] \[r=\frac{\pi +2}{\pi }=1+\frac{2}{\pi }=1+\frac{14}{22}=1+\frac{7}{11}\] \[r=\frac{18}{11}\] \[\therefore \] Diameter \[=2r=\frac{36}{11}=3\frac{3}{11}m\]You need to login to perform this action.
