The circumference is multiplied by √3. Then the correct answer is option B.
What is a circle?
A circle is a two-dimensional geometry on the plane having a center point and the circular line is drawn equidistant from the center point.
The area of the circle is calculated by the formula below:-
A =πr²
Given that the circle has a radius of 5 cm. The area is tripled the effect on the circumference is calculated as:-
A / 3A = π( 25 ) / πr²
r = 5√3
The circumference is,
C =2πr
C =2π x 5√3
C = 10√3
Hence, the correct answer is option B.
