Question

Please help me with this.

Answer 1

56.52 unit squared.

Explanation:

First we know that the radius is equal to 6 thus the diameter would be 12. Now we know to find the whole area we can find the area of the full circle and divide by two. Now we do
`\pi r^(2)` / 2 to find the area of the semi circle. And doing the calculations, we would get 56.52 unit squared.

Equation:
`(3.14  * 36)/(2)`
