Question

if the area of the circle is twice than the perimeter of the circle, then find the value of radius​

Answer 1

$\huge\rm\underline\purple{✩༽ANSWER✩༽}$

We know that,

Area of circle = πr² ----(1)

Perimeter of circle = 2πr ----(2)

_____________________________

Given,

Area of circle = 2 x Perimeter of circle

πr² = 2 x 2πr ----{ from (1) & (2)

πr² = 4πr

r² = 4r

r² / r = 4

r = 4

_____________________________

∴ Radius is 4 units.

Answer 2

Step-by-step explanation:

Area of circle =2× Circumference of circle

πr

2

=2×2πr

r=4

Diameter of circle =2r=8cm
