Question

If the perimeter of a circle is equal to that of a square, then the ratio of their area is *

1 point

a) 22 : 7

b) 14 : 11

c) 7 : 22

d) 11 : 14

​

Answer 1

Step-by-step explanation:

यदि किसी वृत्त की परिधि एक वर्ग के बराबर है, तो उनके क्षेत्रफल का अनुपात * है

2πr = 4a

r= 2a/π

So area of circle = πr²

and area of square = a²

Ratio ::

πr²/a²

= π 4a²/π²×a²

= 4/π

= 4×7/22

14/11

option B .
