Step-by-step explanation:
<em>2) Area of circle = πr²</em>
<em>Area of circle = π*(18/2)²</em>
Area of circle = 81π
Therefore, the area of circle is 81π.
<em>4) Area of triangle = 1/2*base*height</em>
<em>Area of triangle = 1/2*22*33.8</em>
Area of triangle = 371.8 yards
Therefore, the area of the triangle is 371.8 yards.
