Untitled Slide

Square=
Area square = s2
Area square = 42
Area square = 16

Circle=
Area circle = pi × r2
the radius of the circle is 4/2 = 2
Area circle = 3.14 × 22
Area circle = 3.14 × 4
Area circle = 12.56

Since you only have half a circle, you have to multiply the result by 1/2
1/2 × 12.56 = 6.28
Area of this shape = 16 + 6.28 = 22.28
