228/76 = 3
3* 100 = 300

21 + 17 x 2 - 15 + 1 = 21 + 34 - 15 + 1 = 41
Answer:
i think its second one but im not sure
17.41- The formula for the volume of a cylinder is pi radius squared times height. (i.e. the area of the base times the height). You have pi 1.5 squared times height =123. Then you square it so you have 2.25 pi h= 123. then you have 7.065h=123. The you do algebra and you get 17.409, and round it to 17.41.
