Step-by-step explanation:
volume of cylinder formula pi*r²*h
radius of 9cm is 4.5 as 9/2
so 4.5²*15 is 303.75cm
303.75*pi is 303.75picm³
Answer:

Answer:
40
Step-by-step explanation:
This is asking you to plug in the value of h(5) into g(x). First solve for h(5)
x^2-3 = h(x)
5^2-3= 22
h(5) = 22
h(5) is 22. So now, plug that into g(x).
g(h(5)) = 2(22)-4
44-4=40
(g.h)(5) is 40.
The students that are correct are Jake , and Liu because 51, and 21 are composite.
Hope this helps!
AB and BC.
Also, it is EXTREMELY important that you put an arrow facing to the left above AB and an arrow facing to the right above BC.
