Understanding

Application

Calculation

Diagonal of the largest square inside a circle will be equal to diameter of circle.

Since, diameter = 28 cm

Hence,

Diagonal of square = 28 cm

Diameter = 2r

= 14 × 2 = 28

Diagonal of square = a√2

(a = side)

Hence,

a√2 = 28

⇒ a = 14√2 cm

a√2 = 28

⇒ a = 28/√2

⇒ a = 14√2

Area of square = (side)2

Side = 14√2 cm

So,

Area = 392 cm2

⇒ (14√2)2

⇒ 392
