# What will be the area of the largest square that can be cut out of a circle of radius 10 cm?

(a) 100 cm²

(b) 200 cm²

(c) 300 cm²

(d) 400cm²

**Solution:**

Given, radius of circle is 10 cm

We have to find the area of the largest square that can be cut out of the circle.

The diagonal of the largest square will be equal to the diameter of the circle.

Let the side of the square be b.

Area of square = (side)² = b²

Considering right-angled triangle DAB,

By using Pythagoras theorem,

BD² = AD² + AB²

(20)² = b² + b²

2b² = 400

b² = 200

Area of square = 200 cm²

Therefore, area of the largest square is 200 cm²
