Question

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

Answer 1

A circle of radius 10 cm is cut from a square so the diameter of the circle will be the side of square.

Diameter of the circle = 2 × 10 = 20 cm

Now,

Area of largest square from which a circle of radius 10 cm is cut = (side)² = (20)² = 400 cm²
