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

√2000 = √2².√2².√5².√5
√2000 = 2.2.5√5
√2000 = 20√5
(aproximadamente 44.72135955)
-10 and -2
Because -10-2= -12 and -10 x -2 = 20
Hope this helps :)
