Answer:

56.52 units²

explanation:

  • We should know circle's area: πr²
  • Then the semi circle shall have half area, so formula: (1/2)πr²

Steps:

Using the formula:

→ (1/2)πr²

→ (1/2)(3.14)(6)²

→ 56.52 units²

Solution:

Note that:

  • Area of circle: πr²
  • Circle/2 = Semicircle
  • Area of semicircle = πr²/2
  • Radius = 6 units

Finding the area of the semicircle:

  • πr²/2
  • => 3.14 x 6 x 6/2
  • => 3.14 x 6 x 3
  • => 56.52 units²

We can conclude that the area of the semicircle is 56.52 units².
