What is the area of the largest circle that can be drawn inside a square of side 20 cm?

90 π cm²

100 π cm²

110 π cm²

95 π cm²

Answer : Option B

Explanation :

The diameter of the largest circle that can be drawn inside a square = length of the side of the square

As per the question: The side of the square = 20 cm.

So, radius of the circle = 20/2 = 10 cm

Area of a circle = π × radius²

The area of the largest circle = π × 102 = 100 π cm²
