Acompany makes globes with a radius of 11 inches. the material to make the globes costs the company $0.04 per square inch. to the nearest cent, how much does the company pay for the material to create one globe? use 3.14 for pi.
recall the formula sa=4 pi r^2.
$11.05
$60.79
$243.16
$607.90

One globe costs $60.79

Step-by-step explanation:

The area of the globe is

A = 4.π.r^2

Since the radius is 11 inches

A = 4*(3.14)*(11 in)^2 = 1519.76 in^2

We apply a rule of three

1 in^2   $0.04

1519.76 in^2 x

x = (1519.76 in^2/ 1 in^2)*$0.04

x = (1519.76)*$0.04

x = $60.79

x ≈ $60.8

Second Option

$60.79

Step-by-step explanation:

To solve this problem let's suppose that the balloons are spherical

Then the surface area of a sphere is given by the formula:

Where r is the radius of the sphere

In this case we know that the radius of each globes is 11 inches, then:

If the material to make globes costs $ 0.04 per square inch then the cost of a globes is:

.24

step-by-step explanation:

the probability is   .24

the first player had the highest probability of getting a silver marble

the game could be made fair by adding back the marble that was drawn after each draw

answer: 48
