I think the perimeter is 64. If you divided the 4 sides of the window by 256, you get 64. Sorry if it's not right. I hope it is. c;
Answer:
Is not possible to find a prime factorization for m.
Step-by-step explanation:
if

then

So m is not an integer, hence it cannot be decomposed in prime factors.
4/10 × 1/6 = 2/30
You can cross cancel 4 and six...then multiply 2/10 × 1/3 which equals 2/30
If you want you can simplify 2/30 to 1/15
I did most of it for you-
Volume of the cone is 13.1
Volume of the cylinder is 18.9
Now, you just subtract two of the flat circular surfaces, because the two shapes are attached, therefore those parts are not surface area. And there is your answer.
The square roots of 64 is A B and C.
