Question

if numerical value of the circumference and the area of the given circle are equal then what is the diameter​

Answer 1

Answer:

circumference of circle=2πr

area of circle=πr*2

then,2πr=πr*2(given)

r=2

therefore,d=2r

Answer 2

if circumference = area of circle

$2\pi \: r = \pi \: r {}^{2}$

then,

$\frac{2\pi \: r}{\pi \: r} = r$

$r = 2$

then

diameter is 2r
