Question

Find the perimeter of a square circumscribing a circle of radius 10 cm

Answer 1

Step-by-step explanation:

circumference of a circle =2*pi*r

let pi = 3.14

r=10cm

substituting values= 2*3.14*10

=2*31.4

=62.8cm

perimeter of square=62.8 cm

Answer 2

Hello,
When a square circumscribes a circle,the radius of the circle is half the length of the square.
Radius of a circle=10cm
Therefore, Diameter=20cm

Diameter of a circle=Length of the square
therefore, length of square is 20cm

PERIMETER OF SQUARE
=4×SIDE
=4×20
=100
