Which expression represents the volume, in cubic units, of
the composite figure?
pi(5^2)(13) - 5 (5^2)(12)
pi(5^2)(13) – 1 (5^2)(25)
pi(5^2)(13) + (5^2)(12)
O (5^2)(13) + 47 (5^2)(25)

answer: what do you mean

triangle and cube

step-by-step explanation:

hey! so 1 (25) out of 4 (100) is 25 so your answer is 25%. it's like quarters!

to find the perimeter, you add up all the lengths of the sides. in this case you would have to add up 18+22+40+80 which equals 160.
