Best ResponseYou've already chosen the best response.0Do you know that area of circle is\[Area = πr^2\] and the area of triangle is \[Area of \triangle = \frac{ 1 }{ 2 } * base * height\] Then now what you have the two areas with your hands , to get the shaded region you just simply subtract the smaller shape from the larger one , which in this question Larger : the semicircle and the smaller one is the triangle ! Now to calculate just subs. with given values \[Area of semicircle = \frac{ 1 }{ 2 } * π * 5^2 = 12.5 \] And \[Area of \triangle = \frac{ 1 }{ 2 } * 10 * 5 = 25\] Now the shaded region is :\[Area of shaded region : 12.5π  25\] Let me know if you got it :)

Best ResponseYou've already chosen the best response.0I completely understand :) so I subtract 12.5 pi  25 and the answer is 14.26

Best ResponseYou've already chosen the best response.0area of triangle\[=\frac{ 1 }{2 }\times10\times 5=25\] area of semi circle\[=\frac{ \pi r^2 }{ 2 }=\frac{ 3.14\times25 }{ 2 }=\frac{ 78.50 }{ 2 }=39.25\] reqd. area=39.2525=?
