Answer 1

Answer:

Circumference of Circle = 88 cm

Step-by-step explanation:

Question :-

A square board is of size 28 cm . What is the circumference of the largest circle that can be cut out of it ?

We Have :-

Square of side 28 cm

To Find :-

Perimeter of circle

Formula Used :-

Circumference of circle = 2 π r

Solution :-

Side of square = Diameter of circle

28 cm = d

d = 2r

r = 14 cm

Circumference = 2 * 22/7 * 14

= 88 cm

Circumference of Circle = 88 cm

Answer 2

Question :---

• A Square board is of size 28cm as each side .. what is the circumference of the largest circle inscribed in it ?

Concept And formula :---

→ when a Circle is inscribed in a Square than side of Square will be diameter of the circle ..

→ Radius of circle will be = Side of square / 2 .

→ Circumference of Circle = 2 * π * r .

______________________________

Solution :---

→ Radius of circle = 28/2 = 14 cm.

→ Circumference of circle = 2 * 22/7 * 14 = 88cm.

Hence , circumference of the largest circle inscribed in Square will be 88cm..
