Hi there!

The correct answer to this question is: 56.55

Step-by-step explanation:

A semicircle is another way of saying half a circle, if we know the area of a circle is A= π * r^2   then all we have to do is take this equation and divide it by  two to get the area of a semicircle. Additionally since we are given the diameter we need to divide that by 2 to get the radius which is six.

Now we can plug all the components into the equation: A= (1/2)(π)(6^2)

you get 56.55

answer is A

Step-by-step explanation:

A. 24/6 x 10

B. 24/10 x 6

C. 6/10 x 24

D. 6/24 x 10
