Question

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

Answer 1

31.4 inches

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
