Question

if the area of a circle is numerically equal to twice its circumference then find the diameter of the circle​

Answer 1

$\huge \red { \boxed{ \boxed{ \mathsf{ \mid \ulcorner Answer : \urcorner \mid }}}}$

Area of circle = Circumfrence of circle

π r² = 2πr

$\large{\implies}{\sf{{\cancel{\pi}}r^{\cancel{2}} \: = \: 2(2 \: {\cancel{\pi}} {\cancel{r}})}}$

We get

→ r = 4

If radius = 4 units

Then, [ Diameter = 2 × radius ]

Diameter = 8 units

•°• Radius is 4 units & Diameter is 8 units

Answer 2

Answer:

diameter of the circle=8m

radius of the circle = 4m
