Answer:
Best approximation for the circumference of the plate = 18.84 inches
Step-by-step explanation:
Given in the question,
radius of a plate = 3 inches
π = 3.14
To find,
circumference of the plate.
As we know that formula to calculate circumference of a circle given radius
<h2>
2 π r</h2>
2 (π) (3)
2 (3.14) (3)
18.84 inches
So the circumference or perimeter of area = 18.84 inches
<h2>
</h2>
$139.99+ $18.50= $158.49
then you do...
$158.49 - $139.99 and your answer would be $18.50
hope this helped :)
