Remember
difference of 2 perfect squares
a^2-b^2=(a-b)(a+b)
and the undistributiv propeoryt
ab-ac=a(b-c)
so we have

undistribute and factor

cancel out the one ( (u-2)/(u-2)=1)

is result

M α W
M = c1 * W
W α T
W = c2 * T
M = c3 * T

Maybe A I’m not one hundred percent sure but good luck
Answer:
51*pi or 160.221
Step-by-step explanation:
total volume = volume of a cone + volume of a cylinder
total volume = 1/3* pi*r^2* height(of cone) + pi* r^2 *height(of cylinder)
total volume = 1/3 * pi * 3^2 * 5 + pi * 3^2 * 4
total volume = 51*pi = 160.221
