Find the diagram attached.
The area of the remaining pizza will be gotten using the formula as shown below;
Area of a circle = πr²
Area of a circle = π(20)²
Area of a circle = 400π units²
Area of a quadrant = πr²/4
Area of a quadrant = 400π /4 = 100π units
Area of the semicircle and quadrant = 400π + 100π = 500π
Hence the area of the figure is 500π square units
