I am trying to find out what the area of this figure is. I make this formula base×height+π×r^2 by myself and I am not sure if it is right. Can anyone correct me if I am wrong.

Hint: Using Pythagoras theorem, $r=6$ units.
Thus area: $\frac{1}{2}\pi r^2 + \frac{1}{2} b \times h$ where $b$=$2r$ and $h=8$ units

  • I think that is write but when used the 0.5×b×h the result was 96. I thought that the must be 100 because 10×10=100(the sides) – user22634 Apr 29 '17 at 23:41
