To leave something in terms of pi means that you don't have to multiply any numbers by pi when solving; you would just add it to the end. This makes the math much easier to do.
V=pi*r^2*h
V=pi*6.5^2*8
V=338pi

16/21 divided by 4/9 is equivalent to 16/21 x 9/4 = 144/84 which reduces to 12/7. So 12/7 is your answer.
Answer:
Step-by-step explanation:
for y
take 30 degree as reference angle using sin rule
sin 30=opposite/hypotenuse
1/2=9/y (do cross multiplication)
2*9=y
18=y
for x
using pythagoras theorem
a^2+b^2=c^2
9^2+x^2=18^2
81+x^2=324
x^2=324-81
x^2=243
x=
x=9
Simplified answer would be 2 - 9i.
