It should be 50(x+5). Let me know if you want more of an explanation.
The formula to find the volume of a sphere is: V=

Since the diameter is 18 cm, so the radius is equal to r=18/2 = 9
Now we replace r by it's value, so we get:



And we get approximately

Answer:
The answer is volume= 1272
Step-by-step explanation:
volume of a cylinder= pi (3.14)*r^2*h
3.14*9^2*5, 3.14*81*5= 1271.7 when rounded is 1272
