Answer:

165

Step-by-step explanation

One way to find the least common multiple of two numbers is to first list the prime factors of each number. Then multiply each factor the most number of times it occurs in either number. If the same factor occurs more than once in both numbers, you multiply the factor the greatest number of times it occurs.

Which best explains whether point G can be the centroid?

wariber [46]

The answer is C.
Point G can be centroid because 12:6 equals 2:1

FG = 6
FC = 18
so
GC = 12

12:6 = 2:1

I've been trying to get an answer for this all day and don't know where to begin what is the answer like I have no clue

Shtirlitz [24]

so, we have two 54x18 rectangles, so their perimeter is simply all those units added together, 54+54+54+54+18+18+18+18 = 288.

we know the circle's diameter is 1.5 times the width, well, the width is 18, so the diameter of the circle must be 1.5*18 = 27.

$\bf \stackrel{\textit{circumference of a circle}}{C=d\pi }~~ \begin{cases} d=diameter\\[-0.5em] \hrulefill\\ d=27 \end{cases}\implies C=27\pi \implies C=\stackrel{\pi =3.14}{84.78} \\\\[-0.35em] ~\dotfill\\\\ \stackrel{\textit{perimeter of the rectangles}}{288}~~~~+~~~~\stackrel{\textit{perimeter of the circle}}{84.78}~~~~=~~~~372.78$
