2 Calculate the area of the rectangle.
3. Calculate the area of the shaded region. Use 3.14 for π. Round to the nearest hundredth.
Answers
Answer:
1. The area of the circle is 132.67 square centimeters
2. The area of the rectangle is 60 square centimeters
3. The area of the shaded region is 72.67 square centimeters
Step-by-step explanation:
* Lets explain how to solve the problem
- A rectangle is inscribed in a circle, that means the vertices of the
rectangle lie on the circumference of the circle
∴ The diagonal of the rectangle = the diameter of the circle
- From the attached figure
∵ The diameter of the circle = 13 cm
∵ The radius of the circle is half the diameter
∴ The radius of the circle = 1/2 (13) = 6.5 cm
- The area of the circle = πr²
∵ π = 3.14
∴ The area of the circle = 3.14 × (6.5)² = 132.67 cm²
1. The area of the circle is 132.67 square centimeters
- The area of any rectangle = length × width
∵ The length of the rectangle is 12 cm
∵ The width of the rectangle is 5 cm
∴ The area of the rectangle = 12 × 5 = 60 cm²
2. The area of the rectangle is 60 square centimeters
- The area of the shaded region is the difference between the
area of the circle and the area of the rectangle
∵ The area of the circle = 132.67 cm²
∵ The area of the rectangle = 60 cm²
∵ The area of the shaded region = area of circle - area of rectangle
∴ The area of the shaded region = 132.67 - 60 = 72.67 cm²
3. The area of the shaded region is 72.67 square centimeters

Answer:
120 yards 1.
Step-by-step explanation:
In the shape, it is a rectangle with a triangle cut out from it. What is the area of the shape:
Area of rectangle = length × width
12 × 15 = 180 yards²
Area of triangle = ½ × base × height
½ × 10 × 12 = 60 yards²
Now subtract the area of triangle from the area of rectangle:
180 - 60 = 120 yards ²
