Recall the formula SA=472

$3.39

$6.78

$30.52

$122.08

Answer: $30.52

Step-by-step explanation:

Hi, to answer this question we have to calculate the surface area of the ornament:

Surface Area of a sphere = 4π r²

Replacing with the values given:

A = 4 (3.14) (9) ² = 1,017.36in2

Finally, we have to multiply the surface area by the price per square inch of glass.

1,017.36 (0.03) = $30.52
