Answer:

the price of the  bagel is  1.5 $

and a cup  of coffee is 3.5 $

Step-by-step explanation:

6c+12b=39

2c+3b=11.5   |*(-3)

6c+12b=39

-6c-9b=-34.5

---------------------

 /    3b=4.5

so the price of the  bagel is  4.5/3=1.5 $

then 2c+3*1.5=11.5

        2c+4.5=11.5

         -4.5      -4.5

      2c=7  $

  and a cup  of coffee is 7/2=3.5 $

24.4 mL

By converting mm to cm, we get

1 mm = 1/10 cm

18 mm = 18/10 cm

radius (r) = 1.8 cm

To find the volume,

Volume of sphere = 4/3πr3

= 4/3π(1.8)3

Volume = 24.4 cm3

To find the capacity,

1 cm3 = 1 mL

Capacity = 24.4 mL
