Question

please answer with explanation

Answer 1

Hey there !!
____________________________________
Area of circle = 616 cm²

πr² = 616

22 / 7 × r² = 616

r² = 616 × 7 / 22

r² = 28 × 7

r² = 196

r = √196

r = 14 cm
____________________________________

So, radius of circle = 14 cm.

Circumference of circle = 2πr

= 2 × 22 / 7 × 14

= 2 × 22 × 2

= 88 cm.
____________________________________

Given, Perimeter of square = Circumference of circle.

Thus, perimeter of square = 88 cm

= 4a = 88

= a = 88 / 4

= a = 22 cm
____________________________________

Now, area of square = a²

= (22)²

= 484 cm²
