A) \[17.5c{{m}^{2}}\]
B) \[18.5c{{m}^{2}}\]
C) \[20.5c{{m}^{2}}\]
D) \[21.5c{{m}^{2}}\]
Correct Answer: D
Solution :
Area between square and semi-circle = area of square -2 x Area of one semi-circle = \[{{(10)}^{2}}-\frac{2}{2}\times \frac{22}{7}{{(5)}^{2}}\] = \[100-78.5=\mathbf{2}.\mathbf{15}\text{ }\mathbf{c}{{\mathbf{m}}^{\mathbf{2}}}\]You need to login to perform this action.
