Question

Tick the correct answer in the following and justify your choice : if the perimeter and the area of a circle are numerically equal, then the radius of a circle is (A)2units(B)3units(C)4units (D)7units

Answer 1

let radius of the circle =r

if perimeter = area
2πr=πr²
2r =r²----(1)
if r=2
2*2 =2²
4=4

Answer 2

Hey there!

Answer:

$\boxed{\boxed{r=2}}$

Step-by-step explanation:

Perimeter of circle  = 2πr

Area of circle  = πr²

According to the Question,

Perimeter of circle = Area of circle

2πr = πr²

or, 2πr / πr = r

or, 2 = r

or, r = 2

Hence the radius is 2.
