I got this question in quiz.

I want to ask this question from Perimeter and Area of a Circle in portion Area Related to Circles of Mathematics – Class 10

Answer 1

Correct option is (b) 2.74 m

For explanation: The area of the circle (A) = πr^2

6 = \(\frac {22}{7}\) × r^2

r^2 = 1.90

r = √1.90

r = 1.37 m

Diameter of the circle = 2 × radius

= 2 × 1.37

= 2.74 m
