Question

If the area of a circle is numerically equal to its circumference, then the radius of the
circle is
(a) 2 units
(c) 3 units
(d) 4 units
(b) 1 unit​

Answer 1

$\huge\star\underline{\mathtt\red{A}\mathtt\green{N}\mathtt\blue{S}\mathtt\purple{W}\mathtt\orange{E}\mathtt\pink{R}}\star\:$

Area of circle = circumference of circle

=> πr² = 2πr

=> π × r × r = 2 × π × r

=> r = 2 units

Answer 2

Answer:

the radius is 2 because

Step-by-step explanation:

CIRCUMFERENCE OF CIRCLE IS

$2\pi \: r$

2× 3.14 × 2

= 3.14× 4

= 12.56

AND

AREA OF CIRCLE IS =

$\pi \: r \: square$

3.14 × 2 ×2

3.14 ×4

= 12.56
