I'd say it is A but I think you have made a tpyo
It should be 2*PI*radius^2 + 2*PI*radius*height
Answer:
See below.
Step-by-step explanation:
For item 2:
The Net Price Rate = 276 / 460 = 0.60 = 60 % (answer).
Item 3: Net Price Rate = 3247 * 100 / 3820 = 85% (answer).
Item 4 Net Price Rate = 675.11 / * 100 / 987 = 68.4%. (answer).
Item 5 Item's Net Price = 987 * 0.675 = $666.23 (answer).
Item 7 Net price Rate = 2945* 100 / 4750 = 62%. (answer).
Item 8: First find the list place $x:
0.90* 0.80 * 0.70x = 252 ( the 0.90 , 0.80 and 0.70 come from 100 - 10% = 1 - 0.10 = 0.90 and so on)
0.504 x = 252
x = $500
Answer is List Price = $500 and Net Price Rate = 50.4%.
Item 10 List price = 2890.65 / 0.35 = $8259. (answer)
Let length of rectangle=x and width be y
.`. area=x*y
now new length=x+12x/10=22x/10
width=y-y/5=4y/5
now .....
new area=new length-new width=22x/10*4y/5
new area=88xy/50
