A) \[154\,\,\text{c}{{\text{m}}^{2}}\]
B) \[144\,\,\text{c}{{\text{m}}^{2}}\]
C) \[134\,\,\text{c}{{\text{m}}^{2}}\]
D) \[124\,\,\text{c}{{\text{m}}^{2}}\]
Correct Answer: A
Solution :
Circumference of circle \[=4\times 11=44\] \[\therefore \] \[2\pi r=44\,\,\text{cm}\] (By condition) \[\therefore \]\[r=\frac{44}{2\pi }=7\,\,\text{cm}\] \[\therefore \]Area of circle \[=\pi {{r}^{2}}=\frac{22}{7}\times 7\times 7=154\,\,\text{c}{{\text{m}}^{2}}\]
