A circle is inscribed in a square is 10 inch sides what is the circumference of the circle use 3.14 as an approximation for pie
MissTica

Answer:

31.4 inches

Step-by-step explanation:

If a circle is inscribed in a square then diameter of circle inscribed is same as  side as of square.

In the given problem it is given that side of square is 10 inches.

So diameter of  circle inscribed is 10 inches

we know radius of circle is half of  diameter of  circle

Thus, radius of circle inscribed = diameter of  circle/2 = 10/2 = 5inches.

Expression to calculate circumference of circle is given by 2\pi r

where r is the radius of circle.

Thus circumference of  circle inscribed is

2*\pi *5\\=> 10*3.14 \\=> 31.4

Thus, circumference of  circle inscribed is  31.4 inches
