Question

the are of circles is 220cm^.then the area of square inscribed in it is​

Answer 1

Answer:

140cm²

Step-by-step explanation:

Let the side of square be 'a' and radius of circle be 'r'

Ar of circle = 220cm²

πr² = 220

22r²/7 = 22 × 10

r² = 70

r = √70

Now diameter of circle = 2 (side of square inscribed in it)

(2 × √70)² = 2a²

4 × 70/2 = a²

a² = 140

Now, ar of square = (side)² = a² = 140cm²
