Find the Area of the figure
sineoko [7]
The figure is made up of two semi-circles and one triangle

--------------------------------
Find Radius
--------------------------------
Radius = Diameter ÷ 2
Radius = 5 ÷ 2 
Radius = 2.5 ft


Area of the semi-circle = 1/2 πr²
Area of the semi-circle = 1/2 x π x (2.5)²
Area of the semi-circle = 9.82 ft²

Area of the triangle= 1/2 x base x height
Area of the triangle = 1/2 x 6 x 4
Area of the triangle = 12 ft²

Total area = 9.82 + 9.82 + 12 
Total area = 31.63 ft²

--------------------------------------------
Total Area = 31.63 ft²

The perimeter of a triangle is 56. The side lengths are x + 4, 3x + 7, and x + 9. What is the value of x?
Sidana [21]
<h3><u>Answer:</u></h3>
  • x = 7.2
<h3><u>Step-by-step explanation:</u></h3>
  • Perimeter: Side 1 + Side 2 + Side 3

  • => 5x + 20 = 56
  • => 5x = 56 - 20
  • => 5x = 36
  • => x = 7.2
<h3><u>Conclusion:</u></h3>

Therefore, the value of x is 7.2.
