Question

if the circumference is numerically equal to 3 times the area of circle find the radius of the circle

Answer 1

let the radius of the circle =r

circumference = 3* area

2*pi*r = 3*pi* r^2
(2*pi)/(3*pi*)= r^2/r
2/3=r
therefore
radius =r=2/3 units

Answer 2

Answer:

Circumference = 2πr

Area 3 times = 3×πr^2

3×πr^2 = 2πr

R = 2/3 units
