Question

when the circumference and area of a circle are numerically equal then the diameter in numerical equal to​

Answer 1

Answer:

diameter is 4 units

Step-by-step explanation:

circumference of the circle

$2\pi \: r$

area of circle

$\pi {r}^{2}$

if both are equal, we will get

$circumferece = area \\ 2\pi r = \pi {r}^{2} \\ r = 2$

radius is 2 units then diameter will be 4 units

Answer 2

Area of Circle=Circumference of circle

πr² =2πr

r²/r= 2π/π

r= 2

Now Diameter = 2×r

d = 2×2

d = 4 units
