Question

The circumference of a circle with a radius of 1 is 2π. Set up a proportion to find the circumference of a circle with a radius of 6.

Answer 1

Answer:

The circumference is equal to $12\pi\ units$

Step-by-step explanation:

we know that

by proportion

$\frac{2\pi}{1}\frac{circumference}{radius} =\frac{x}{6}\frac{circumference}{radius}\\ \\x=6*2\pi\\ \\x=12\pi\ units$

Answer 2

Answer:

The circumference of circle is 12π units.

Step-by-step explanation:

Given the circumference of a circle with a radius of 1 units is 2π.

we have to find the circumference of a circle with a radius of 6 units.

we know that by proportion

$\frac{Circumference}{Radius}=\frac{Circumference}{Radius}$

$\frac{2\pi}{1}=\frac{Circumference}{6}$

$Circumference=2\pi\times 6=12\pi units$

The circumference of circle is 12π units.
