Question

When the circumference and area of a circle are numerically equal then the diameter is numerically equal to

• A. area
• B. circumference
• C. $2\pi$
• D. 4

Answer 1

The correct option is D 4

Since, Circumference = area
$\therefore 2\pi r=\pi r^2$
$\Rightarrow \Rightarrow r=2$
So, Diameter =2r = 2 x 2 =4
