Question

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

Answer 1

Answer:

8 UNITS

Step-by-step explanation:

let the radius of the circle = r units

area of the circle = 2* circumference

pi*r^2 = 2*2*pi*r

r^2/r =4*pi/pi

r=4

diameter = 2r

d=2*4

d= 8units

Answer 2

let the radius of the circle=r units area of the circle= 2 circumfarence

pi*r^2=2* 2* pi*r
r^2/r=4*pi/pi
r=4
diameter =2r
d=2*4
d= units
