Question

if radius of a circle is π/2 unit then circumference of that circle is? ​

Answer 1

Answer:

Well the circumference of a circle is equal to 2pi * the radius

C=2pi * r and if you no the radius then C= 2pi * 2pi= 4 pi sq

Answer 2

Answer:

$\pi^{2}$

Step-by-step explanation:

Here, Radius of circle = π/2

So, Circumference of the circle = 2πr

= 2×π×π/2

= π^2
