we know that
The surface area of the square pyramid using a net, is equal to the area of a square plus the area of its four lateral triangular faces
so
![SA=16^2+4[\frac{1}{2}(16)(13)]](https://tex.z-dn.net/?f=SA%3D16%5E2%2B4%5B%5Cfrac%7B1%7D%7B2%7D%2816%29%2813%29%5D)
3.5555555556 / the third one
Area of a circle is pi x r^2
R is the radius which is have the diameter: r = 10/2 = 5
Area of the full circle would be 3.14 x 5^2 = 3.14 x 25 = 78.5 square units.
A semi circle is half a full circle
Area of the semi circle = 78.5/2 = 39.25 square units.
