From the attachment,
AD = AE, so FA is a median.
BD = BF, so BE is a median.
CF = CE, so DC is a median.
And G is the centroid.
From the properties of centroid, we know that
The centroid divides each median in a ratio of 2:1
So,
So, GB will be units
Answer:
12.5 pi or 39.26990
Step-by-step explanation:
First we can find the radius, which is half the diameter, 5 feet. To find the area of a semi-circle we would find the area of the circle and then divide by 2:
We can substitute what we have:
This gives us:
12.5 pi or 39.26990(Not sure what format you need it in)
