Question

10 ft
8 ft
D
Find the area of this figure. Round your
answer to the nearest hundredth. Use
3.14 to approximate “pi”
A = [? ] ft2
Notice that only half of the circle is included in the figure!

Answer 1

The Area of the Rectangle = l × w

<> 10 × 8 = 80 ft²

The Area of the Semicircle = ½

The Area of a circle = ½ (πr²)

<> π = 3.14

<> r = ½ of 8 = 4 ft

<> ½(3.14 × 4) = 6.28 ft²

The Area of the figure = Area of rectangle + Area of semicircle:-

<> 80 ft² + 6.28 ft² = 86.28 ft²

Therefore, The area of the figure is 86.28 ft².

Answer 2
