Question

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

Answer 1

Area of circle = pie r^2

circumference = 2 pie r

As they are equal

pie r^2 = 2 pie r

R^2 - 2 R = 0

R( R- 2) = 0

R = 0,2

As R can't be 0

so it's 2

Answer 2

given: Area of circle = Circumference

TPT : r

2πr=πr²
:.r=2
