Answer:
15
Step-by-step explanation:
Ok so first you need to know how to calculate the volume of a cylinder
I will put the formula here: V=πr2h
Since pi is equal to 3.14 as said in the problem we can simply divide 282.6 by pi, the radius and 2
That is equal to 282.6/3.14*3*2
A little calculation shows that, the answer is 15
Hope this helps :)
