Question

what is diameter of a circle equal to its circumference and area are numerically equal​

Answer 1

Step-by-step explanation:

put the area and cicumference equal

you will get

r=2unit

d=4unit

Answer 2

Answer:

4 units

Step-by-step explanation:

Area of circle = πr².

Circumference of circle = 2πr.

Area = Circumference

πr² = 2πr

r²    = 2r

=> r = 2 units.

Hence the diameter = 2r = 2 * 2 = 4 units.
