Question

6

Answer 1

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.

Answer 2

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
