A company makes glass lawn ornaments with a radius of 9 inches. The glass to make the balls costs the company $0.03 per square inch. To the nearest cent, how much does the company pay for the glass to create one omament? Use 3.14 for
Recall the formula SA=472
$3.39
$6.78
$30.52
$122.08

$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

Feel free to ask for more if needed or if you did not understand something.

the answer is:

the correct option:

b.

to solve the problem, we need to remember how to operate to simplify exponential expressions using the logarithms.

we are given the equation:

then, using placing logarith with base 7 on both sides of the equation, we have:

so, rounding the obtained result to two decimal places (nearest hundreth), we have:

hence, we have that the correct option:

b.

have a nice day!
