Answer:
B 236in³
Step-by-step explanation:
you use the equation
V=πr²h/3
π=PI r=Radius h=height
Sense in this problem they give you diameter instead of radius you want to divide it by 2 to get one half.
so the equation used looks like this:
3.14•5²•9/3=235.5
rounded up is 236in³

Answer:
That would be sina.
Step-by-step explanation:
sin(a+b) = sinacosb + cosasinb
sin(a-b) = sinacosb - cosasinb
Adding we get sin(a+b) + sin(a-b) = 2sinaccosb
so sinacosb = 1/2sin(a+b) + sin(a-b)
