First you find the area of the circle, the formula is A=3.14(radius squared) so in this scenario it’s 3.14(4•4) 4 squared is 16, so now we have 3.14(16) which is 622.976, we round that to get our answer of 623

Step-by-step explanation:
I the given triangle, it appears that M and N are the midpoints of the segments BG and BD respectively. If it so, then let us solve it.
By mid segment theorem:
2MN = GD
2(6x - 51) = 114
12x - 102 = 114
12x = 114 + 102
12x = 216
x = 216/12
x = 18
