3. Given the equation determine:
f(x)= x² - 4
f(-3)

5

Step-by-step explanation: F(-3)=(-3)^2 -4

(-3)^2=9

F(-3)=9-4

F(-3)=5

The amount of water in the cylinder in term of π is: 504 π.

Step-by-step explanation:

Volume of cylinder () = π

where, r= radius of cylinder

h= height of cylinder

so,  = π× ×15

=540 π

Now, volume of ball () = ×  π ×

=  × π ×

 =  36π

Amount of water in the tank=   -

=540 π- 36π

=504 π

Youre answer is D
