Question

If the circumference and the area of a circle are numerically equal, then diameter of the circle is
(a)$\frac{\pi}{2}$
(b) 2π
(c) 2
(d) 4

Answer 1

Answer:

The diameter of the circle is 4 units.

Among the given options option (d) 4 is the correct answer.

Step-by-step explanation:

Given :  

Circumference of the circle = Area of the circle  

2πr = πr²  

2r = r²

2 = r²/r

2 = r

r = 2 units

Radius of the circle ,r =  2 units

Diameter of the circle,d =  2 × radius  

d = 2r

d = 2 × 2

d = 4 units  

Diameter of the circle = 4 units  

Hence,the diameter of the circle is 4 units.
