explain as best answer will get but make ur answer short and sweet plz.

(a)  Volume of  1st cup  =  (1/3)pi *(4/2)^2 * 8  =   32/3 pi in^3

 scoops  =  (2000/3)pi / ( 32/3) pi  =  2000/32  = 62.5  =  63

(b)  Volume of  2nd cup  =  (1/3)pi *(8/2)^2 * 8  =   128/3 pi in^3

scoops  =  (2000/3)pi / ( 128/3) pi  =  2000/128  = 15.625  =  16

Option: B is the correct answer.

The simplest inequality that represents this situation is:

                 B.      x > 9

It is given that:

Luke can build 2 tables in a day.

Also ,  he has to build more than 18 wooden tables for a client.

i.e. if he works for x days.

Then the total number of tables he build is: 2x

i.e.

( Since he has to build more than 18 tables)

i.e. on dividing both side of the inequality by 2 we get:
