Answer:
26.13 [tex]ft^{2}[/tex]
Step-by-step explanation:
Half circle :
Area of a circle = [tex]\pi r^{2}[/tex]
A = 3.14 ([tex]3^{2}[/tex]) = 9(3.14) = 28.26
That's a full circle. We want half. Divide by 2 = 14.13
Triangles. Both are same.
A = [tex]\frac{(b)(h)}{2}[/tex] = [tex]\frac{(3)(4)}{2}[/tex] = [tex]\frac{12}{2}[/tex] = 6
There are two of them, so area of triangles is 12
12 + 14.13 = 26.13
