The radius of the larger circle is 40 inches.

Get first the circumference of the smaller circle.
C = 2πr; Where π = pi; r = radius
    = 2(3.14)(16)
C = 100.48

Now get the circumference of the bigger circle using ratio:
   2/5 = 100.48/C
   2C = 502.4
2C/2 = 502.4/2
     C = 251.2

Using the circumference, compute for the radius of the larger circle:
r = C/2π; Where C = circumference; π = pi
  = 251.2/2(3.14)
  = 251.2/6.28
r = 40

To check:
      C = 2(3.14)(40)
251.2 = (6.28)(40)
251.2 = 251.2

Natali [406]

Answer:

b. $342

Step-by-step explanation:

Base = Length * width

Base Area = 12 * 5

B = 180 square inches.

Perimeter of the prism will be :

P = 2 (length) + 2 (15)

P = 2 * 12 + 30

P = 54 inches

Height of the jewelry container will be :

X = Ph + 2B

X = 54 * 6 + 2 * 180

X = 684 square inches.

Total cost for paint of jewelry box is :

X * cost per inch

Total cost = 682 * $0.50

Total Cost = $342.
